Parametric Bed Corner Clip

Just a quick corner clip I made in OpenSCAD.

Instructions:
- Open file in OpenSCAD
- Set `bed_thickness` to the thickness of your bed (including glass plate)
- Change `wall_thickness` to a multiple of your nozzle thickness (default for 0.4 nozzle)
- Render (F6)
- Export as STL

Print recommendations:
- Set wall thickness to the be the same as what you put in the model
- Set bottom thickness to be the same as wall_thickness in the model
- Infill 100% (just in case)
