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.

Messy power adapters and cable sprawl are one of the fastest ways to make a workspace feel chaotic—especially when that workspace isn’t permanent. The Logical CableNest was designed to solve exactly that problem.

CableNest is a ventilated cable management box that contains power adapters and cables while keeping them organized, cool, and easy to move. It’s designed to sit neatly behind a computer or notebook screen, but it works just as well anywhere you need to tame cable clutter.

What It Is

CableNest is a 100% 3D-printed, snap-together containment box for power bricks, chargers, and excess cable length. Open hex-pattern walls allow heat to escape while keeping everything visually contained and out of the way.

All CableNest models share the same height and depth, with multiple widths available to suit different setups—from compact laptop workspaces to multi-monitor desks.

How It Works

Power adapters load through the hinged split top, cables are routed out either end, and the ventilated walls allow heat to escape during use.
Once closed, CableNest keeps cables organized, concealed, and accessible when needed.

Because everything is contained in a single unit, the entire setup can be picked up and moved—ideal for shared tables, hot-desking, or temporary workspaces.

In Use

Placed behind a monitor or notebook, CableNest largely disappears from view while still keeping power accessible. Opening the top provides immediate access to adapters and cables without unplugging anything.

CableNest is equally at home in:

• Shared family workspaces
• Home offices
• Maker desks
• Temporary or mobile setups

---

Modular by Design

CableNest can be used entirely on its own, or paired with the optional Logical DeskBox, which sits neatly on top and adds tool and desk-accessory storage. Together, they form a compact, portable desk system—but each component also works independently.

Assembly & Printing

• 100% 3D printable
• Snap-together design
• No hardware required
• Assembly is identical across all sizes

Detailed assembly, disassembly, and usage diagrams are included with the download.

Sizes Available

CableNest is available in multiple widths, all sharing the same height and depth.
Different widths allow you to scale the system based on the number of power adapters and cables in your setup.

Note: Listings show a representative size. Various sizes are available.

Why CableNest Exists

CableNest was designed around a simple idea:
power management shouldn’t force you into a permanent desk.

By containing cables in a ventilated, movable box, CableNest helps keep workspaces tidy without sacrificing flexibility.

I use utility knives all the time in the shop — opening boxes, trimming prints, cutting filament, breaking down packaging — and I wanted something that felt solid, safe, and predictable, without relying on tiny springs, metal hardware, or complicated internals.

That’s what led to SLUK: a fully 3D-printed, self-locking utility knife designed around simplicity, reliability, and everyday use.

What Makes SLUK Different

The defining feature of SLUK is right in the name: self-locking.

Instead of a traditional spring-loaded slider or button lock, SLUK uses geometry and friction to lock the blade carrier in position automatically. Once extended, it stays put. When retracted, it stays put. No extra parts, no tiny mechanisms, and nothing to wear out quickly.

It’s a very “3D-printing-native” solution — using shape, tolerance, and material behavior instead of hardware.

Designed for Standard Utility Blades

SLUK is designed around standard utility blades, which are inexpensive, widely available, and easy to replace. The blade is fully enclosed when retracted, and the body provides a comfortable grip without being bulky.

The goal wasn’t to reinvent the utility knife — just to make a clean, functional version that prints well and works reliably.

Printing and Assembly

This design is intentionally straightforward to print and assemble.

• Fully 3D printed
• No supports
• No metal hardware
• Simple press-fit assembly

PLA works well, and PETG or ASA are also good options if you want a bit more durability. As with most functional parts, decent wall thickness matters more than extreme infill.

The tolerances are forgiving, but like most sliding parts, good extrusion consistency helps.

Why I Made This

There are lots of utility knives out there — cheap ones, fancy ones, disposable ones. What I wanted was a printable tool that earns a permanent place in the shop, one that’s easy to understand, easy to maintain, and safe to toss in a drawer or toolbox.

SLUK is the result of that thinking: simple, solid, and designed to work the way you expect it to.

Give It a Try

If you print one and put it to use, I’d love to hear how it holds up for you. Feedback, tweaks, and edge cases are always welcome — that’s how these designs get better over time.

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.

Click here to download STL (Affiliate Link)

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!!

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…
