Under Desk Laptop Mounting Brackets

I got tired of my laptops always being on top of my desk connected to their docks. Between work, personal, and business, it was just getting too messy with 3 of them floating around getting swapped in and out. There are several designs out there but for one reason or another I just didn't feel like it would fit for my purpose needing to support multiple different laptops and not just one specific brand. So I made just a generic, heavy-ish duty, version for myself and though I'd share if others might have a similar need.

I work with Inspiron 16's, Macbook Pro 16's, and Dell Pro Max 16's. so I needed something that would work with thinner (Apple) laptops as well as chonky (Pro Max 16) laptops. You can pick whatever width you want when you mount this so it should really fit just about any laptop out there, except maybe a Panasonic Toughbook. I also mount my laptops on the long edge and still have plenty of support for the whole laptop, though if you mounted on the short edge you'd have probably nearly complete support.

Each mount has 3 screw holes. Depending on the type of desk you have, you maybe only need two per mount, but since so many desks are made of cardboard and paper filler (including mine) it didn't hurt to have the third for extra peace of mine. The holes in the bottom of the mount are for your screwdriver to come up through and connect with the screw. The mounting hole is 2mm recessed and spread out wide to support a low profile truss head type screw instead of a more tapered or chamfered countersink screw as most of the large thread particle board screws seemed to be more commonly a truss head.

I printed mine in PETG on a Bambu Labs P1S (door open, all fans on 50% or higher) because that's what I had extra of laying around the house. 6 outer walls. 0,20 height. Basically, the Bambu Lab default "Strength" profile, I just added about 10mm of brim to be safe since this prints vertically so the weakest joint is down the length of the mount and not any of the mount or shelf unions. So if it cracks or splits it will be along a vertical line, but the integrity of the mount should remain and not drop your laptop out.

Designed in Fusion 360, by hand - no AI, and I've included the F360 .f3d file, as well as a SketchUp .skp file. Because I just slapped this together real quick, it's not parametric, but you should be able to fit it to your needs pretty easily still if you want to remix it at all.

You're hanging a laptop in the air with something you 3D printed. Use your best judgement when picking what you print it with, how you mount it, etc. I don't want anyone's laptop falling and getting damaged. So, insert some fancy lawyer warning here or something, to use at your own risk, and make good decisions.
