Description

UPDATE 06.01.2026
Added longer bottom parts for wider PC cases - 22cm/8,5in, 23cm/9in and 25cm/10in. New planks has increased wall loops amount just in case. I haven't printed increrased one myself, added them due to request in the comments. They should be same, as I basically just extended them in the middle.

Changed infill pattern in the Print profile to gyroid.

Reclaim your floor space and elevate your setup! This Under-Desk PC Holder is the perfect solution for keeping your computer case safe, clean, and out of the way. It's especially useful for height-adjustable standing desks, as it holds the PC in place and prevents your cables from being pulled or strained when you move the desk up or down.

I designed this holder to be both incredibly strong and easy to install:

Engineered for Strength: Each arch is designed and printed to support a load of up to 15 kg. I've been using it with my own PC printed in PLA for over two weeks without any signs of stress. For extra peace of mind, printing in PETG or a stronger material is also a great option.
Adjustable & Versatile: The two-piece design means the length is fully adjustable to your PC case. The width between the arches is 195mm, comfortably fitting any case up to 190mm wide.
No Glue, No Fuss Assembly: The parts connect using a clever, tight-fitting inclined joint, holding everything together securely without a single drop of glue.
Simple & Smart Installation: Installation is a breeze! The top parts are designed for 4mm screws, and I've included modifiers in the print file to easily adjust the hole size.
Handy Installation Tool: To make life even easier, the print profile includes a small assist tool to help you perfectly mark the screw spots under your desk. No more awkward holding and measuring!
My Reliability Promise: I have full confidence in this design. Should my own mount ever fail, I will immediately update this post's title and description to let the community know.

Print it now! Download the STL files or use the ready-to-print profile for your Bambu Lab printer. The profile includes all parts, the installation assist tool, and the modifiers for customizing the screw holes. You can either assemble the holder first or attach the top pieces to your desk and then slide the vertical parts into place.

Could you add a bottom piece that allows for a roughly 8.5in pc case?

The designer has replied

@tiarin_hino

I'm gonna be on vacation starting from next week. so I would look into it. as long as it is fitting on a print bed it should be fine

@tiarin_hino

Took me longer than I thought due to holidays, but I haver updated Print Profile to include wider bottom planks - 1 with 8,5in internal width and another with 9in internal width. I have also included helper tools for both of them. Decided to add version that is 0,5in wider than Case you requested in case of tighter fit. Please let me know once you printed if that fit.

Thank you!

@user_909422324

I really like your mounting system. But i do have trust issues with 4mm screws... that might be just me hehe Yet i do not find the modifier to adjust the screw holes. Any hint for a newbie?

The designer has replied

@tiarin_hino

so basically what you want to do to increase size of the screws is to add negative cylinder modifier, place it where screw holes are, center it and make the diameter to the size of the screw you want +0.2mm for the clearance. also make sure that screw head part is also adjusted, for that you can adjust the size of existing negative cylinders (if you are using Bambu studio). if you are using other slicer that just add negative cylinders for the head part same way as for the shaft.

The print quality is really good, but I need to constantly check if it's going to fall apart. Should I apply glue to the joints

That's normal for you o worry and it's a good idea of checking it constantly. My PC is is set up like this for 5 month already and haven't broke. As promised in my description, should my PC ever fell down, I would immediately update this page iwth it. No, you don't need glue for the joint, they are esigned in a way that holds them together using sheer frictions and pressure. Since joint are inclined downwards but are wider in the end, they get stuck together without glue. And without using glue you have advantage of changing elements easily.

@Wheele
