Small items have a way of taking over a workspace — pens, earbuds, glasses, sticky notes, charging accessories, and all the everyday things you reach for repeatedly throughout the day. Before long, the desk feels cluttered even when nothing major is out of place.

The Logical DeskBox was designed to bring intentional organization to everyday desk essentials while keeping everything easy to access, compact, and portable.

What It Is

DeskBox is a 100% 3D-printed, snap-together desk organizer featuring a cantilevered upper tray and a spacious main compartment below.

When the lid is opened, the tray lifts automatically, giving clear access to both storage levels. Frequently used items stay visible and within reach in the upper tray, while bulkier or less frequently accessed items are neatly stored below.

Everything is contained in a single, compact unit that can be easily picked up and moved when needed.

Why the Cantilevered Tray Matters

Traditional desk boxes often turn into deep bins where small items disappear into the bottom. DeskBox solves this by separating storage into two functional layers:

• Upper tray for daily essentials like pens, earbuds, and small accessories
• Lower compartment for larger or less frequently used items

As the lid opens, the tray lifts automatically — no digging, no stacking, and no lost items.

Designed to Work Alone or as a System

DeskBox can be used completely on its own as a compact desk organizer, but it was also designed to pair perfectly with the Logical CableNest.

When stacked on a matching-width CableNest:

• DeskBox organizes everyday desk items
• CableNest contains power adapters and cable clutter

Together, they form a clean, portable desk system — ideal for shared workspaces, home offices, and flexible setups where everything needs to be easy to move and quick to tidy.

Each component also works independently, so the system can be built up over time.

Modular Sizing

DeskBox is available in multiple widths, all sharing the same height and depth. The different sizes allow you to scale storage based on your workspace and the amount of desk essentials you keep close at hand.

Smaller sizes work well for compact setups or minimalist desks, while larger versions provide generous storage for multi-device or maker-style workspaces.

Each DeskBox width has a corresponding CableNest designed to match it for clean stacking.

Assembly & Printing

DeskBox is designed with the same principles used across LogicalPlanet projects:

• 100% 3D printable
• Snap-together design
• No hardware required
• Designed to be disassembled if needed
• Assembly is identical across all sizes

Clear diagrams are included to guide assembly, disassembly, and everyday use.

Why DeskBox Exists

DeskBox was created to solve a simple but persistent problem:
the small things on a desk rarely have a proper home.

By giving everyday essentials a compact, accessible, and intentional storage space, DeskBox helps keep workspaces calm, functional, and easy to reset — whether you work at a dedicated desk or a shared surface like a family table.

It is a super simple 1-piece print. And, it attaches by simply placing it behind a wall plate. The existing wall plate screws hold the wall plate and the Mini eShelf in place with considerable strength. Definitely adequate enough for small electronics or similar.

A complication I discovered after designing my first one and getting a few followers to test it was, not all wall plates are the same size. So I have created a few size variants to hopefully allow it to work for most people.

On the top back centre of the shelf is a recess (pass through hole) so that electrical wires can be container when using the Mini eShelf for charger or similar activities.

Print Settings

Functional designs (such as this one) generally require more strength than non-functional designs and more strength than the typical default slicer settings provide, so please review your slicer settings carefully.

This product was designed for a 0.4mm nozzle and a 0.2mm layer height. For best results, I suggest the following:

Assembly and Installation Notes

No assembly is required. It is ready to go right off the print plate. And, installation is a breeze. Simply unscrew your existing wall plate and then place the Mini eShelf behind it. Screw the original wall plate back into place. That’s it!!

I’m not entirely sure how I arrived at designing this. I just had a thought in my head that a self-closing beverage holder would be fun. It started as something completely different, but once I got on the design that it is now, I just loved it. It is so satisfying to play with and fun to keep a drink concealed and cool in.

As it stands now, it is one of my favourite designs. I think I feel that way because of the collapsing iris design that I created. While it is really just one element of the design and may be lost on many, it is very slick. The blades of the iris are compounding so that they can collapse into a smaller space than the radial distance of the opening. I am definitely going to try to find other applications for that!

And, I managed to get the iris to activate by the vertical movement of the upper section of the DrinkColder. This is another area of design that fascinates me… using human power in a way that is almost not even noticed. In this case, by pressing down on the DrinkColder in a very natural way you receive the beverage but at the same time, you are moving the machine inside.

I have often thought about how we open and close doors in the same way giving up some energy every time we do it; how can that be harnessed and used?

Anyway, back to the DrinkColder… the other aspect of this design that I really love is the counterweight effect of the top and bottom moving halves which makes the whole thing work. And, when a drink is removed the DrinkColder stays open for it to be returned to.

No motors, no springs — just effective geometry, balance, and symetrical gears.

Features

• Fits standard 355ml (12oz) cans
• Includes optional cozy insert or TPU ice ring mold to keep your drink extra cold
• Uses internal counterbalance and gears for motion — no electronics
• Designed for PLA with no supports required
• Visual assembly guide included
• Dimensions: 114mm x 114mm x 167mm (4.5” x 4.5” x 6.6”)
• Top iris opening: 70mm diameter

Print Settings

Functional designs (such as this one) generally require more strength than non-functional designs and more strength than the typical default slicer settings provide, so please review your slicer settings carefully.

Since posting the DrinkColder, I had someone point out that printing with 2 different layer heights will help parts slide better in situations like this design. I will experiment with that and post an update when I can.

Post Printing and Assembly Notes

Deburr any sharp edges after printing. And, use light lubrication at rotating joints.

GearBin is a fully 3D printable mini trash bin with a unique mechanical twist. Designed for use with biodegradable dog waste/poop bags as liners, it’s the ideal solution for food scraps, backyard clean-up, BBQ prep, or anywhere you want a tidy, compact bin that works smarter – even your desk.

I chose to use biodegradable dog waste/poop bags for this because they are a fraction of the cost of biodegradable kitchen bags and smaller so you can discard them more frequently at a lower cost.  

Our issue is we do not want to waste the more expensive biodegradable kitchen bags so we try to use them for several days. But by the end of a few days the kitchen waste can start to smell to then you throw it away without filling the bag… wasteful. So back to the small dog poop bags that are much lower cost and the right size for daily discarding.

The GearBin could be ideal for a wide range of applications including:

• Office or desk
• Kitchen countertops
• Outdoor prep areas and BBQ stations
• Composting and daily food waste
• Eco-conscious homes using dog poop bags for liners

The main features of the design are:

Gear-Driven Push Lid:
Open the lid with a simple press on the front bar—no electronics, just clean, mechanical magic.

Folding Liner Frame:
The innovative push-push mechanism folds the bag frame inwards for easy loading and unloading of liners. Holds standard dog poop bags securely.

100% Snap-Fit Assembly:
No glue, screws, or springs. Just print, snap together, and you’re ready to go.

Optional Bucket Insert:
Use with or without a removable bucket insert (included) to catch leaks and assist with liner removal.

I watched a reel promoting a small garbage bin with a folding frame to make it easier to install the liner bag. I thought that was a great idea so that is what I did too. But I made it using a push-push style so you can press it once to collapse the frame and then again to open it once the bag is installed. And, you can do the same to remove the bag.

I have also included a bucket that sits in the GearBin and essentially creates a safe space for the bag. It makes sure the bag can be pulled out from the GearBin even if it is jam-packed. And, that in the event the bag breaks or leaks you have a containment system. But the bucket also means you can use the GearBin without a bag.

I have included some exploded diagrams to help visualize what the GearBin is but to assemble it, you need to watch my instructional video linked at the bottom of this post.

Print Settings

You can print everything in PLA but you should consider printing the spring components in PETG. I have identified those in the print settings table below.

Functional designs (such as this one) generally require more strength than non-functional designs and more strength than the typical default slicer settings provide, so please review your slicer settings carefully.

This product was designed for a 0.4mm nozzle, a 0.2mm layer height. For best results, I suggest the following:

Assembly Notes

I have linked my assembly instructional video below, so please check that out. But also note there are a few pieces of print support to be removed after printing.

The Lid has a small strip of print support that sits under the print-in-place hinge. So look for that as you loosen the hinge after printing.

As well the Bucket has print support on each side to create the handle holes. Carefully break those free before using.

If you are building the GearBin you will definitely need to watch the following assembly instruction video…

It isn’t so much about a car mounted version but rather making a 100% printable clamping phone holder. I mean, I think I can make this for the car but so far this is a desktop version that is also compatible with my ClampDock mount.

To make this all work, I needed a compact set of compliant springs that could clamp the phone securely and adapt to a fairly wide range of phone sizes. I also had to add in a gear which interfaces between the two spring sides so that they move in parallel and the exact same distance. Once these are put to gether you have the ClampDock. And, then various mounting options can be added.

As noted above, so far I have made an arm assembly that can hold the ClampDock at a desk, side table or similar. It uses a series of indexing “click” joints that can hold the arm assembly at variaous angle and in various positions. And, it can be free standing or attached to my ClampDock assembly.

Print Settings

Functional designs (such as this one) generally require more strength than non-functional designs and more strength than the typical default slicer settings provide, so please review your slicer settings carefully.

This product was designed for a 0.4mm nozzle, a 0.2mm layer height. For best results I suggest the following:

• Material = PLA for everything but the Springs which should be PETG and the boots for gripping the phone which should be TPU.
• Nozzle = 0.4mm
• Layer Height = 0.2mm
• Line Width = 0.4mm
• Wall Count = 4 (1.6mm)
• Top and Bottom Layer Count = 5
• Detect Thin Walls = ON
• Wall Generator = Arachne
• Infill = 40% (Cubic)
• Support = None required
• Print orientation = As per the STL/3MF files and the included image

Assembly Notes

This wedge operates in two ways allowing it to accommodate an under-door gap from 8mm to 60mm. It is thin, light and strong making it ideal for any handyman or tradesperson who needs a door wedge with them.

It is a print-in-place design that requires nothing after printing. Simply take it off the build plate and put it to use.

Simply fold the two sides together (they are limited to 100° angle) and stand it up under a door. Pull the door onto it and voila! The door is stopped.

I used a 15° angle for the stop which creates a fairly low rise making it easy to wedge under doors. But that slow rise means one side does not cover a very large range – only 8mm to 35mm. So I made it two-sided allowing the second side to carry on with an additional range for holding more doors – 33mm to 60mm.

Printing

This product was designed for a 0.4mm nozzle, a 0.2mm layer height and the following settings:

Material: I choose to use PETG for its durability and flexibility
Wall Line Count = 4 ( 4 x 0.4mm = 1.6mm walls )
Top and Bottom Layer Count = 5 ( 5 x 0.2mm = 1.0mm top and bottom )
Infill = 100% for maximum strength (minimum 40%, Cubic)
Ironing = OFF (not needed)
Support = No support required
Brim = NO (If you have to use a brim, set it to “outside only”)
Material = PETG recommended (any material should work fine)
Print Orientation: As shown below.

Assembly Notes

No assembly or post-print processing is required.

This product is much simpler than my previously posted USB Cable Theft Deterrent allowing it to be much stronger and robust. The entire product is a 1-piece print-in-place design.

I recommend printing this in the most durable material you have and can print with. The idea is you want maximum strength. And, to that end, your slicer settings are very important. Don’t use the default slicer settings which usually are designed for speed with 2 walls and only 15% infill or so. For all my functional designs especially this one, I recommend a minimum of 4 walls, 5 top and bottom layers, and 40% infill… 100% infill for this product.

Obviously, to be secure this USB Cable Lock needs to be secured to something else too big to be stolen or moved. A table, a pipe in the wall, a chair, anything heavy and big should do. You will want a strong cable, chain or another means to secure the device that is at least as strong as the lock and the device.

Instructions

Using the clasp is quite simple, open it, lay the cables in, and close it. Then place a lock’s shackle through the hole and attach the entire set to something. The lock shackle can be up to 6.35mm (1/4″) in diameter.

Printing

Material: I recommend PETG because it has some flex and will withstand a little more abuse in this context.  However, any material should work.

My Setting:

• Nozzle = 0.4mm
• Layer height = 0.2mm
• Line width = 0.4mm
• Wall count = 4 (1.6mm)
• Top and Bottom Layer Count = 5
• Infill = 100% for maximum strength, minimum 40% Cubic
• Ironing = ON Everywhere (to help separate the stacked layers)

Support:
Designed to print without slicer-generated support. Required support is incorporated into the design.

Print Orientation: As shown in the screenshot(s).

Assembly Notes

No assembly or post-print processing is required other than carefully removing the print support as described in the accompanying image.

I have actually designed 2 versions of this concept. The first one I am referring to as a “USB Cable Theft Deterrent”. A) Because for the most part, you only need to deter this type of theft. And, B) Because I designed it to be super simple and easy to deploy (which kind of makes it not super effective as a “locking device”).

And, that is why I have developed a second version, the “Lockable USB Cable Clasp”. Not shown in this blog post, the second version is lockable – I mean, you can put a lock on it. This version is designed to be more suitable for extended absence from your chargers and more likely to lead to the charger cable still being there when you return. I will post that one as soon as it is done.

This design is print-in-place and would benefit from being printed in the most durable material you have. The idea is you want maximum strength. And, to that end, your slicer settings are very important. Don’t use the default slicer settings which usually are designed for speed with 2 walls and only 15% infill or so. For all my functional designs and especially this one, I strongly recommend a minimum of 4 walls and 40% or more infill. Let’s face it, it is plastic so no matter how strong we make it, it will not be too difficult to defeat but I do not want to make it too easy.

Regardless of which version you choose to use, you will need something to lock the device to. A table, a pipe in the wall, a chair, anything heavy and big should do. For the USB Cable Theft Deterrent, I am also providing a simple 3D printable strap that you can use to attach the device to larger objects. I am including a 180mm long and a 230mm long strap. So the photo to understand how that works.

For the Lockable USB Cable Clasp, you will want a strong cable or an other means to secure the device that is at least as strong as the lock and the device.

This is a generally straightforward product design and requires only the top Pen Holder portion to be snapped onto the Base. The Pen Holder seems to float on the Base because it is balanced on the small pointed apex of the Base. As long as the load of pens is relatively balanced the Pen Holder spins freely and quietly.

I designed a Gripper ring with a fine zig-zag’ish pattern on the bottom and it turned out to work quite well. It can be installed in the Base to help create a little bit of stickiness so that the Base is less inclined to spin on the desk surface. It works brilliantly but of course, must be printed in TPU or something similarly soft. And, if you do not have TPU handy it works quite well without it too (as long as your desk surface is not too smooth).

The Gripper ring press fits into the groove in the underside of the base and can be a bit of a tight fit. Use a small screwdriver or similar to get it installed if necessary.

I had loaded the Pen Tower up with various pens and similarly shaped objects of varying weights and they all seemed to perform well. It will even spin with just one heavy pen in it.

Printing

I have tried to make my main print settings visible on the Cura screenshot but in case they are difficult to read I have summarized them again here…

Material: I don’t think it will matter what material you use for the Pen Holder and Base. I used PETG. You can opt not to use the Gripper but if you do it must be printed in TPU

My Setup:
Nozzle = 0.4mm

My Settings:
Layer height = 0.2mm
Line width = 0.4mm
Wall count = 4 (1.6mm)
Infill = 40%

Support:
Designed to print without support. No support is required.

Print Orientation: As shown in the screenshot(s).

Assembly Notes

The components should all snap and press together as per the accompanying diagram without any post-print processing.
