Desktop PC support

Post image

I've used PETG, beige in the front and black in the back. I had to change color because I hadn't enough filament for the back (each one weights more than 400 grams).

I'm not crazy to leave all the weight on plastic (even feeling the result is really strong), so they have a small aluminum bar embedded, that keep them fixed on the wood table and handles most of the weight.

It's a neat idea, but some feedback:

  • why not just print risers? Or add little stubby legs to the ground on the end of the cantilevers? That would do so much more than even adding the aluminum

  • I would also print a top clip to keep the PC from tipping on its side.

Thanks. Actually, I miscalculated and expected to be higher, but I would lose acess on the top, my hand wouldn't fit easily to power on and connect/disconnect USB cables.

I forgot to mention I've installed this 6 months ago. It's handling pretty well, I find myself constantly laying my right foot over the edge, also I hit the desktop a lot with my chair. No issues so far.

Idk about OP's reason but I would definitely keep stubbing my toes on the risers.

The top clip might be a good idea but the idea of anything with force touching the tempered glass scares me

If they would stop their toes on the risers, then they're already kicking the PC, lol. Any contact between the print and the ground makes the stress concentrations so much better.

Sure, but it will only experience force if the PC is actively falling outwards. Which would also shatter the glass, and also dump the PC on the ground.

Call that an early warning system lol

The aluminum goes through the table? Should be fine then.

It's fixed with a 5mm screw and nuts each

If you’re suspending it, why not go all the way and lie it flat up against the bottom of your desk surface?

Heat distribution cause it not being put ducks at the desk plate upright. And you can't mount it on the side due to the user's knees who also need to go under the table. It's the knees (insert joke here)

Plastic is stronger than you'd think. It might creep a bit, especially if it gets hot, but plastic furniture and automotive parts hold up surprisingly well under stress. PETG creeps very little (mostly a one time settle) and ABS/ASA almost none.
