This peg/pin will help you secure something, such as a gridfinity base with screw holes, to a plywood sheet, like those often found in desk drawers. Where a screw isn't suitable because the plywood is thin, this peg might work.
Beware, this model is not very good. When I print a batch of these about half fail to print correctly, and 1/8th break as I use them. But enough “worked for me” and maybe they'll work for you - or maybe not. Good luck!
Print it with a higher-than-usual temperature to get better layer adhesion, drill out your hole with a 3mm drill bit. Then shove this through the two things you want to join. It'll take effort and you may break a few but they work for me.
I don't know how easy they are to remove because I don't want to remove them :D
See my Gridfinity base too!
