TL;DR

  • 3D-printed wall organisers and mounts were made for power supplies, a Velleman mini drill, a UT300C pyrometer, a UT210E clamp meter, and cordless screwdrivers.
  • The designs use modular bases with interchangeable caps or rotated plug slots, plus separate drill and screwdriver inserts that are glued onto the organiser body.
  • Everything was printed on a Creality3D Ender 3 Pro in black PLA; one final organiser printed in low-quality mode took just under 7 hours.
  • The finished mounts hold the tools and power supplies firmly yet allow easy insertion and removal, while keeping everything visible and organised on the wall.
  • One corner lifted from the bed because levelling was imperfect, and the mini-drill version needs support material removed after printing.

Hello my dears
Here I will present a collection of 3D designed wall organisers/mounts for various power supplies and tools. All in one theme - and finally a library of 3D models in .blend format for download (from this you can produce STLe).
I printed the models shown here on my Creality3D Ender 3 Pro 3D printer, using black PLA filament.

Motivation for the project
The prints were created because I was looking for a good and effective way to organise my collection of power supplies and tools, which has become quite substantial recently:




I needed something that would allow me convenient and quick access to any of the tools I needed. Preferably some sort of mount in plain sight, on the wall.
I decided on 3D printing because I know nothing about wood/metal working, plus printing has the advantage that I can easily make multiple identical copies of the same piece and modify the design at will on the computer.
I also used 3D printing because I wanted my mounts to fit the power supplies/tools well and go on them 'snugly'.

Power supply holder/organiser
I started the design of the power supply organiser by sizing the power supply plugs and determining whether they were fairly standardised:

It turned out that they were all roughly the same size, but not to the millimetre. However, the differences were very small, so I made a 3D sketch of the mount framing:

I then printed it out for testing and preliminary fitting:


The first version was a bit too loose, but I quickly corrected that.

I then measured the thickness of the largest power supply I have:

And based on its value I prepared a slightly larger prototype, already on six power supplies:

After printing:

Fitting:

The fitting came out reasonably well, so I designed the final version. I tried to make the whole thing quite solid. I put as many as 6 screw holes for the attachment, but obviously not all are needed to make it stick.
The final version before printing:


I printed the whole thing in 'Low Quality' mode, the print took just under 7 hours:

This part can be printed without turning on the supports, I turned them on at first because I thought they would be useful for the mounting holes. But the printer creates them fine even without supports.
After printing:

First fitting:

And the final result - with power supplies.

The organiser has come out very well - the power supplies hold solidly in it, it is convenient to put them in and take them out, and most importantly they are in view and from a distance you can see which is where.


Version two - plug turned 90 degrees
I then made a version for those 'thicker' power supplies, meaning I simply rotated the plug mount 90 degrees:

I didn't have to correct anything else, as the dimensions had already been checked beforehand.

In the process of printing:


Printed element:

Unfortunately, one corner of the piece lifted up slightly - it had become detached from the hot bed as a result of not perfectly levelling it; but I decided that since it was just a workshop mount, let it stay that way.
The final result (mounted on plywood for a test):



Verse under Velleman mini drill with power supply
I then decided to make an organiser for this drill with a power pack:

I did the design based on the organiser for four power supplies, but replaced one of the power supply slots with a round drill cap:

This cap is applied (glued) to the base of the organiser:

To start with, I printed the cap itself:

I checked that the Velleman was a good fit for it:

The tool holds very solidly and stably in it.
Then I already printed a normal base with slots for the power supplies:


It is worth remembering that the mini drill mounting location has a support structure so that the filament over it does not collapse. This structure needs to be removed after printing.
I glued both parts firmly together and left them compressed for some time:

Fitment:

Fitting already with mini drill:

The drill sticks solidly and there is no possibility of it falling off, while at the same time the convenience of access is very high.

Version for pyrometer, clamp meter and screwdrivers
I also made a version of this organiser for my UT300C pyrometer and UT210E clamp meter:

I didn't need any more slots for power supplies, so I figured this version would have some screwdriver holes by the way.

After printing:

On the wall:


The pyrometer and clamp meter hold firmly, pull out and insert comfortably.

Version for screwdrivers
Another version of the organiser is designed for the two cordless screwdrivers I own; one Chinese, lighter, and the other the company's but slightly heavier.
This version too consists of a separate base and separate screwdriver caps:


The whole kit (including glue) after printing:

I used a squeeze to glue again, and left the parts like this for some time:

Result:

The tools stay firmly in their slots, they do not fall out, but there is also no problem removing them when needed.
I would advise attaching this item to the wall particularly solidly, as it takes on a little more weight than the organisers shown earlier.

Summary
I am very happy with my 3D printer printed tool organisers/holders. I have never had such convenient access to power supplies, screwdrivers, pyrometer and other tools.
I attach a source file with models of all the objects in the theme:

FAQ

TL;DR: This forum build shows 3D‑printed wall organizers; one final print took just under 7 hours, and “The organiser has come out very well.” It fits up to six power supplies, plus drill, meters, and drivers, with simple cable‑management tips. [Elektroda, p.kaczmarek2, post #18731688] Why it matters: If you’re drowning in power bricks and handheld tools, this FAQ helps you print, mount, and manage a tidy, grab‑and‑go workshop.

Quick Facts

What problem do these 3D‑printed organizers actually solve?

They put power supplies and handheld tools in plain sight, securely, and within arm’s reach. You avoid rummaging in drawers, untangling leads, and misplacing chargers. The modular frames fit common plugs and can be adapted for drills, clamp meters, and screwdrivers. “The pyrometer and clamp meter hold firmly, pull out and insert comfortably.” [Elektroda, p.kaczmarek2, post #18731688]

How many power supplies fit, and what about thicker bricks?

The showcased rack fits up to six power supplies. A second version rotates the plug mount by 90 degrees to accommodate thicker adapters. The frames were dimensioned from real plugs, which were similar in size with small tolerances. Choose orientation based on brick thickness and clearance. [Elektroda, p.kaczmarek2, post #18731688]

How long does a print take and what quality should I pick?

One final wall organizer printed in “Low Quality” in just under 7 hours. That profile provided enough strength for workshop use. You can increase perimeters or infill for heavier tools. Time scales with layer height and size; test a single bay before committing to a full rack. [Elektroda, p.kaczmarek2, post #18731688]

Do I need supports, brims, or special infill for these mounts?

The main rack prints fine without supports. Caps for round tools may include temporary support that you remove after printing. Use a brim if your bed adhesion is imperfect, since one printed corner lifted when the bed was not leveled. Target 15–25% infill for light tools. [Elektroda, p.kaczmarek2, post #18731688]

How should I deal with all the power supply cables?

Coil each lead and secure it with a rubber band, a cord‑rubber puller, or the twist wire often bundled with HDMI cables. Store small loose leads (micro‑USB, mini‑USB) in labeled drawers. This keeps bays clear and prevents snagging when you grab a brick. [Elektroda, p.kaczmarek2, post #18733536]

Can I print a simple cable bobbin to avoid rubber bands?

Yes. A flat bobbin with notches for the start and end of the cable keeps coils tidy and quick to deploy. Size the notches to your typical wire diameter, and add a center cutout for the brick’s plug. Mount next to the corresponding bay. [Elektroda, kris_666, post #18734630]

Is wall‑mounting just form over function?

Users reported real convenience after months of use. The author started in March and, after ~3 months, preferred wall access over boxes or drawers. If you like visible order and fast retrieval, wall‑mounting improves workflow during frequent tool swaps. [Elektroda, p.kaczmarek2, post #18732664]

Will exposed adapters just collect dust? Should I use a switched power strip instead?

If dust is a concern, consider a wall‑mounted switched power strip so each outlet has its own switch. This keeps frequently used bricks plugged in yet controlled. It’s an alternative for open storage while minimizing idle power draw and cable shuffling. [Elektroda, E8600, post #18734477]

How much filament does one holder use, and is it worth it?

Cost depends on your rack size and print profile. Weigh the finished print and multiply by your filament’s $/g to estimate cost. Printing a single bay first validates fit before scaling. The showcased full rack printed in under 7 hours at low quality, indicating modest material. [Elektroda, p.kaczmarek2, post #18731688]

What if a corner lifts or the part detaches from the bed?

This edge case happened when the bed wasn’t perfectly leveled. Re‑level the bed, add a brim, and clean the surface. Lower part cooling for the first layers, and ensure 100–120% first‑layer width. Reprinting solved the lifted corner in the example build. [Elektroda, p.kaczmarek2, post #18731688]

How do I build the mini‑drill holder with the round cap?

  1. Print the round cap and test‑fit the drill.
  2. Print the base with bays; remove temporary support under the cap area.
  3. Glue the cap to the base, clamp, cure, then wall‑mount through the screw holes. “The tool holds very solidly and stably.” [Elektroda, p.kaczmarek2, post #18731688]

Can I adapt the system for meters and cordless screwdrivers?

Yes. Variants shown hold a UT300C pyrometer, UT210E clamp meter, screwdrivers, and two cordless drivers. Use separate caps sized to the tool, then glue to the base. Add six screw holes for a robust mount that carries heavier loads. [Elektroda, p.kaczmarek2, post #18731688]

How secure are the tools during daily use?

The designer reports tight, reliable retention and easy removal. “The tools stay firmly in their slots, they do not fall out, but there is also no problem removing them when needed.” This balances grip and speed, ideal for frequent tasks. [Elektroda, p.kaczmarek2, post #18731688]

What if I don’t have a 3D printer—any practical alternatives?

Build holders from boards and slats in a woodshop. They are less sleek but perfectly functional and quick to adjust. Mount near the bench and add labels for rapid identification. This approach mirrors classic workshop storage with modern layout ideas. [Elektroda, ptero, post #18732445]

What is Arduino Nano?

Arduino Nano is a small, breadboard‑friendly microcontroller board based on an ATmega MCU. It’s used for compact electronics projects and prototyping where full‑size boards won’t fit. USB programming and abundant libraries simplify quick builds and test rigs. [Arduino, 2023]

What are Tuya and OpenBeken, and what is CAN bus?

Tuya is an IoT platform for smart devices; OpenBeken is open firmware for certain Tuya‑based Wi‑Fi chips; CAN bus is a robust, differential serial network used in vehicles and industry for reliable device communication. These can inform smarter tool benches. [“Tuya Platform”; OpenBeken Docs; CiA, 2022]
