Parametric Ender 3 Bed Clips

I have the official Creality borosilicate glass bed, but I flipped it over and installed a PEI sheet. I wanted a bed clip that had a good bit of tension to hold the bed down, but none of the clips I found on Thingiverse were tall enough. Trying to scale them up was a bit of trial and error that I wasn't up for.

So this is my first stab at trying to make a parametric object in FreeCAD. It's designed so that it will firmly grip my bed surface. The opening can be adjusted for the thickness of the glass. The length of the arms can be adjusted to have more or less margin around the print bed-- 10mm seemed reasonable for my needs. I'm including the FCSTD file so people can remix easier.

All in all, these seem pretty solid. If anyone has any suggestions on how to improve, I'm all ears!
