under desk keyboard holder

keyboard holder designed to take a standard M3 wooden screw. there is aproximately 2cm inside the hole so if you had a 3cm screw 1cm would be sticking out the bottom. im currently using on a mechanical keyboard on PLA, ive knocked it with my knees and so far no issues, id personally increase wall thickness to 5 and run a gyroid infill if you want to be extra but not essential. hope this helps :)
