Filament Spool Holder

The filament spool holder on my Monoprice Maker Select is too short for standard 1 kg spools.
There are other designs on Thingiverse, but I decided to roll my own.

This holder will accept regular spools, up to 70 mm wide. The threaded section on the holder is M30x2, and the threads are long enough to allow mounting in any web up to about 5 mm thick.

I haven't included the .scad file because I'm using my own thread library for this, and this isn't the place to publish that. Maybe later.
