Screw on foot

This is a foot for a 3D printer or whatever item that accepts a screw from the top to hold it in place. It is customizable so that you can adapt it to your needs. It will now accept a screw from the bottom now too. You just have to set the height the same as the screw_depth.

You should keep the screw hole less than the diameter of the screw by a little bit so that you have some material for the threads of the screw to dig into.
