Summary

I printed it in petg at 3 walls and it works fine. It would probably be fine at 2 walls, that's what I intended to start but I accidentally left old settings in Cura.The screw holes should be big enough for M4 countersunk, or one smaller, I think.

Edit : I added a second slightly thicker socket. The first one works great in petg, but it squeeks. I redid it in nylon but it's not quite strong enough, so the thicker one is for nylon. Do at 100%.
