7 Under-desk headphone hanger

No more cords hanging off the edge

Start simply with a headphone stand or a hanger mounted beneath your desk. This print is a game-changer if your headphones are constantly in the way or getting tangled. Most designs use either screws or adhesive to attach under the desk and feature a hook wide enough to hold even bulky headsets securely. PLA is fine for this print, but PETG offers more durability if you tend to bump things.

Choose a design that fits your style — some even have integrated cable holders or double hooks for multiple pairs. Mount it within easy reach of your primary sitting position, and you’ll never have to sweep your headphones off the desk again. It’s one of the quickest prints to make, but the impact is immediately noticeable.

You’ll also find designs that accommodate audio cables or accessories like headphone amps. If your desk has a lip, look for clamp-style hangers that don't require any screws at all. This one small upgrade keeps your audio gear safe, clean, and accessible.

6 Monitor arm cable clips

Secure and sleek cable management for screens

If you have articulating monitor arms, you’ve probably noticed how cables can hang awkwardly or get tugged when you move the screen. 3D-printed cable clips solve that problem. These snap directly onto the arm’s frame, holding the cables snugly and preventing droop without limiting movement. Then it's just a matter of routing your display and other cables through the clips.

You can find designs tailored to nearly every monitor arm profile, including square, round, oval, and other, more proprietary shapes. Be sure to measure before printing to get a snug fit. PETG is an excellent choice for this project since it provides enough flexibility to snap in place but won’t break with repeated use. Some designs even include guides or locking tabs for multiple cables.

Once installed, you’ll immediately notice how much cleaner your setup looks. Everything stays in line, and the cables move with the monitor rather than trailing behind. It’s a small detail with a surprisingly big visual and practical payoff.

5 Desk-mounted USB hub bracket

Makes every port easy to access

You probably rely on a USB hub, but hate how it clutters your desk. A 3D-printed bracket lets you mount it underneath the desk, giving you all the necessary access without the mess. Whether you choose a design that screws in or uses double-sided tape, this quick upgrade gets your ports right where you want them.

Brackets are available for all sorts of popular hub sizes, and many include vents or clips to help with cooling and cable management. You can print in PLA if your hub stays cool, but PETG or ABS are better if it tends to heat up. A well-placed hub makes it easy to plug in flash drives, peripherals, or even your phone charger without reaching behind your PC. I know locating a USB port can be challenging sometimes, and this helps you keep your hub easily at hand without contributing to the clutter you want to get rid of.

Mount it near the front edge of the desk for maximum convenience. Your cables will be better organized, your desk will be cleaner, and your workflow will never be interrupted by fumbling for ports again.

4 Vertical laptop dock

Clean up your clamshell laptop setup

If you dock your laptop but leave it lying flat on the desk, you’re wasting prime workspace. A 3D-printed vertical stand lets you store it on its edge, clearing the surface while keeping it safe and accessible. Designs with adjustable widths are convenient, ensuring a snug fit without scratching your device.

Most stands can be printed in PLA, though PLA+ or PETG will give you more strength. You can also find versions that include channels for airflow or cable routing underneath. Vertical docks are perfect for clamshell mode, making it easy to connect to one USB-C cable and get to work without opening the laptop.

Once you make the switch, you’ll wonder why you waited so long. Your laptop will be better protected, your desk will feel less cramped, and the setup will look more intentional and professional.

3 Under-desk power strip holder

Hide messy cords without losing access

Power strips are essential, but don’t have to be an eyesore. A 3D-printed mount can attach your strip to the underside of your desk, keeping cords off the floor and out of sight while still giving you full access to the plugs. It’s one of the most satisfying prints regarding cable management.

You’ll find both open-clip and full-enclosure designs. The open clips are great for strips you might want to remove, while the enclosed types hold everything firmly in place. PETG or ABS is the way to go here for safety and strength, especially since power strips and adapters can get warm during use.

Mount it toward the back or side of your desk to keep things tidy but reachable. This minor tweak will go a long way toward cleaning up your setup and will make vacuuming or adjusting cords much easier.

2 Microphone arm clamp extender

Solve bad placement with a little reach

If your boom arm doesn’t sit right on your desk or has the reach you need, a printed extender can fix that. These mounts lift and shift the arm outward, giving you better placement for recording, streaming, or video calls. They also reduce strain on the clamp and can improve stability.

You’ll want a sturdy print for this — PETG is ideal. The extender should match your desk thickness and the clamp type of your mic arm, so take a few measurements before printing. Some designs also add forward tilt or height to help position the mic closer to your mouth without awkward angles.

You’ll get more precise mic placement, better sound, and a cleaner look overall. If your current setup is less than ideal, this upgrade is worth the print time.

1 Wall-mounted tool and accessory rack

Offload clutter without losing convenience

Sometimes, the best way to organize your desk is to take things off it. A wall-mounted modular rack can store tools, drives, cables, and other essentials within arm’s reach but not in your way. These systems use a rail or peg-style base, with individual mounts that snap in and out as needed. TheGridfinity system can be especially helpful, since it's modular and almost infinitely customizable.

Print just what you need at first: a screwdriver holder, a flash drive organizer, or a cup for loose accessories. Later, you can expand the system with more pieces. These are usually PLA-friendly since they don’t bear much weight, but you can switch to PETG for extra toughness if needed.

It’s a smart way to get more functionality from the vertical space around your desk. The flexibility makes it easy to adapt the rack to your specific tools or accessories and keeps your desktop blissfully empty.

Small prints, big improvement for your workspace

A few thoughtful prints can completely change how you interact with your desk. These mounting solutions don’t just organize — they make the space more usable and enjoyable daily. Whether hiding cables, freeing up space, or making your gear more accessible, 3D printing gives you the power to shape your workspace exactly how you like it.
