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.
- Simply download, print, and enjoy.
If your specific thumbscrew requirements are different from those used in this object, I recommend downloading jridley's OpenSCAD script and playing around with the values to get exactly what you need.
