Ultimate Power Brick/Supply Holder (Parametric)

So I started a project to organize the mess under my desk.   So I found the Underware 2.0, project (https://makerworld.com/en/models/783010-underware-2-0-infinite-cable-management?from=search#profileId-1504508).   I like the project and used the OpenGrid version (https://makerworld.com/en/models/1175037-underware-for-opengrid?from=search#profileId-1195039), since it required less printing and less connectors (I liked the snap in cable runs).

The only thing is that I really couldn't find anything suitable for the holding power bricks or power supplies to the underside of the desk.  The ones you could find are not the right fit, or the right type of connectors.   I had 3 different supplies and more to come.

Update 2/7/2026

There is now a Version 2.0 with additional features and some fixes.   Find it here https://makerworld.com/en/models/2364960-parametric-electronic-mount-underdesk-wall-etc#profileId-2587874

So I built an OpenSCAD project to create holders for the power bricks.   Made it parametric, so I could do different sizes.  Also made is simple because I just wanted the brick to slide in, and not have to deal with where the cords coming in and out and where they were located (the power cords varied in location).

So after the getting my stuff built, I thought I could extend it to handle the popular mounting grids (I had most of the code done).   So I did a remix for OpenGrid, HSW and Multiboard.

So I gave it an mount type to do the following

• OpenGrid Lite (https://makerworld.com/en/models/1175037-underware-for-opengrid?from=search#profileId-1195039)
• OpenGrid Full
• Screws (#8 Flatheads).
• HSW Vertical (https://makerworld.com/en/models/22521-honeycomb-storage-wall?from=search#profileId-27457)
• HSW Horizontal
• Multiboard (https://www.multiboard.io)

Also a thanx to BlackJackDuck (https://www.printables.com/model/1002471-multiboard-snap-backer-generator-parametric/files), that provided the OpenSCAD for the Multiboard Snaps.

If I missed anyone please let me know and I will update the text.

So the parameters (mm)

• Length of the Power Brick
• Width of the Power Brick (side to side)
• Depth of the Power Brick (front to back)
• Thickness (how thick do you want the walls to be, 3 is a good value).
• Grip Width (these are the section of the front that hold the brick, you could make the wide enough to close it).  
• Backstop Height (the back stop keeps the brick from sliding out on a vertical mount, you  can adjust this to give clearance to the power cord).
• Mount Edge (how much room to allow for the mount to the edge, adjusting this higher will cause less mounting points).

Future, I need to adjust the mounts so that it can handle longer bricks or power strips. so the mount points can spread out more.  Also probably need to allow more holes for screws.

I have tested all the 1 and 2 mounting point models, have not tested all the 3 point ones.

Note:  I have included a project to use as a base, import your generated file to it.   It should print fine with PETG/PLA, I used PETG for anything that is hanging.   The best orientation to print is straight up, with the backstop on the plate.  You will need supports for connectors.

If you decide to generate models for specific power supplies and publish them, that is great, but please refer people back to this project and any of the mount projects (like HSW, Multiboard, etc.).

If you find problems with the generator please send me a chat, I will fix them.
