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.

Over the last few years, toilet paper manufacturers have been steadily shrinking the inner cardboard core. That doesn’t sound like a big deal… until you realize that a lot of holders (especially simple or minimalist ones) rely on a fairly consistent core size to work properly.

My original tank-mounted toilet paper holder worked great for years. Then suddenly rolls started falling off, rattling around, or just not fitting the way they used to. That’s what led to this second-generation redesign.

What Changed in Gen 2

The biggest difference in this version is the post itself.

Instead of relying on a rigid diameter that assumes all TP cores are the same, the Gen 2 design uses a compliant, flexible post that adapts to different core sizes — including the smaller modern ones. It grips the roll securely without binding and without needing springs, bearings, or hardware.

The rest of the design stays true to the original goals:

• Fully 3D printed
• No hardware
• No supports
• Simple, functional, and easy to print

It still mounts directly on the back of the toilet tank, keeping the roll accessible without drilling holes or installing wall brackets.

Single and Double Roll Versions

I’ve included both single-roll and double-roll variants.
The double version is surprisingly handy — not just as a backup roll, but also if you like having different paper types available.

Both versions use the same compliant post idea, so they handle modern rolls equally well.

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 Notes

No assembly required.

Why This Update Matters

This is a good example of why I like iterative, real-world design. Nothing about toilet paper holders is glamorous — but when something that used to work suddenly doesn’t, the fix needs to be simple, reliable, and durable.

Gen 2 exists because the world changed slightly, and the design needed to adapt.

Try It Out

If you’ve noticed rolls slipping off older holders or not fitting the way they used to, this version should solve that problem cleanly. As always, feedback is welcome — especially if you run into edge cases or unusual roll sizes.

What I ended up with is this fully 3D-printed, modular wall-mounted spool storage system. It’s snap-together, it’s expandable in all directions, and the spool trays actually collapse up into the wall assembly when I need my wall space back. It’s been a game changer in my workspace.

What This Is

This system is designed to hold standard 1 kg filament spools and let you build as much storage as you need without a bunch of screws, brackets, or bulky racks. The trays are printed parts that rotate up into their housings, creating a compact footprint while still being easy to access. The rail system makes it easy to keep multiple rows aligned and expandable.

It’s perfect for:

• Print farms
• Compact workshops
• Maker spaces
• Anyone who hates tangled filament and messy shelves

How It Works

1. Build the Walls
   Snap the wall components together — they key into each other so you know everything is aligned properly.
2. Assemble the Trays
   Each tray part has a keyed rotation so it sits square in the wall assembly and can pivot up or down smoothly.
3. Mount to Rails
   Slide the assembled trays onto the rail system. You can add more rails and spacers to widen or stack more rows.
4. Collapse for Space
   Want the wall back? Just rotate the trays upward flush against the wall rails.

This system isn’t locked into any particular number of spools — you add as many as you like by linking rails and adding spacers.

Printing Notes

As with most of my functional designs, strong walls and good infill give the best results. I’ve been printing these in PLA with the following general settings:

The trays and rails print reliably without fiddly supports, which makes batch printing them for a larger system quick and predictable.

The hook is rotatable and extends out for use and in for collapsing into the main body. The two side arm sections also fold into the main body for storage or travel.

This design uses compliant latches to hold the compartments closed. I might try to make a combination lock version in the future. And, a few people have requested a thicker body (bigger storage).

Once deployed, the hanger is full-size.

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.

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!!

When I designed the first crates, my skills were too limited to make these new ones. But it is very gratifying to now be able to design and print a 100% printed, snap-together, strong, modular system for organizing things, such as in a freezer, in a pantry or just on the shelf.

This crate system has multiple wall lengths so you can make crates of varying lengths. And, what’s more, I have now made 3 widths so you can file almost any width or depth of shelf.

The crate Ends are identical and allow walls to be snapped into them through a vertical channel on the back side. The walls can be removed and changed by releasing a small tab which locks the wall into place when in use.

A Connector is also available that allows walls to be joined end to end between the End components, allowing the crate to be extended.

Different wall lengths can be combined to create an almost unlimited range of total crate lengths.

Crates that are the same width and length are also stackable.

I wanted a better way to keep a couple of dog bags with me, especially in the summer when I don’t have a jacket and all the accompanying pockets. As any dog owner likely knows, if you put a couple of loose bags in your pocket it is hard to tell if they are there or not and eventually you find yourself out for a walk and your pockets are empty. And, when you put loose dog bags in your pocket they become messy catching with anything else in your pocket. So my idea was a credit card-sized bag holder that would allow you to keep the bags organized and know that you have it before you set out.

I have worked on this for a long time but it only finally became clear to me recently when I realized a stand was a good idea and then the winder could be stored there. The winder can also be kept inside the PcoektBagCard but because it takes up precious space that means 1 less bag. Abd, with the stand able to hold 3 PocketBagCard, you can have them standing by and ready whenever you want to grab one to go.

The PocketBagCard itself is two pieces that are hinged together and print-in-place resulting in a very strong hinge and no assembly required.

The stand holds up to 3 PocketBagCards and has storage for the winder.

Using It

The idea is to wind a few bags around the Winder with a corner of the first bag extended out. By doing so, the bags will uncoil from the middle of the coiled bags and easily and neatly dispense from the PocketBagCard. So you hold a corner, wrap the bags and then slide them off the Winder.

Then place the coiled bags into the PocketBagCard with that exposed corner peaking through the gap in the hinged end. Fold it closed, and you are ready to dispense.

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.

I have so much I want to say about this project….  Firstly, I started thinking about the old Pez dispensers.  Super fun and simple but after a lot of time I allowed myself to veer away from that idea.  Despite that, it still has a few throwback elements from the Pez dispenser concept.  Secondly, and more importantly, when I started focusing on 3D printable designs many years ago, I dreamt of a day when I might feel the confidence to design functional machines.  And, while this one is not epic in nature, it really marks a moment in time for me where I have switched to thinking about and being able to design more complex machines.  The implementation of gears combined with my new love for compliant mechanisms opens the door to creating more interesting (and challenging) projects.  Third, I feel this is a good educational project because it does incorporate a lot of mechanical design elements.  It can be assembled and disassembled, allowing anyone who wants to to really play with the design and study how it works.  Great for young ones to get their hands on and hopefully get inspired.

While everyone might not need a dog treat dispenser (or candy dispenser) I hope most people will appreciate the complexity of the design and its capacity to help us dream bigger with our 3d printers.   This project has about 30 parts to it.  That also makes it my most complex operating design (I say that because I have designed puzzles with more parts, but that does not really count). 

Here are some of the design features incorporated into this project:

• Compliant compression and leaf springs
• Full and partial double helical gears
• Cam-driven gate
• Double helical rack and pinion
• Adaptive hook design on the delivery system
• Removable crumb tray
• Loading cartridge

I originally designed it for the Costco Kirkland Signature Chicken and Rice Formula Dog Biscuits (6.79 kg).  These dog biscuits come in a large cardboard box and, therefore, are not that convenient to have handy.  So I thought about creating a dispenser for them, and even the idea of making it a design the dogs could self-serve from (when given permission).  I think that could work.  

The biscuits are held in a Pez-like loader, which I can modify for other biscuits, treats or object sizes.  The loader is the only part that needs to be modified for dispensing things in a range of sizes as long as it is smaller than the original biscuit size.  I have included a simple box container that can be used to hold smaller items to dispense as well. The included dispensible box has a volume of 102 x 43 x 14 mm
