Heated Bed Thumbscrew

Created using the OpenSCAD script by jridley, this object has been optimized to serve as a thumbscrew to hold an M3 nut on the underside of a heated bed. It is also a thin as practical, so that the heated bed needs a minimum of clearance (giving you the largest possible Z height).

I use 4 of these per MendelMax 1.5 printer.
