Maker Box Minimal Spool Holder

UPDATE:14May19 - MakerBoxSPThread30 and MakerBoxSPTop30 added, these are used to create a M30x4 threaded spool that can be used with the threaded hub from the Universal Auto-Rewind Spool project https://www.thingiverse.com/thing:3338467


This is a minimalist spool holder, designed for Maker Box sample spools, also used for small leftovers from my larger spools. The hardware is M3 nuts and 16mm Socket Head screws (14mm-18mm should work) and I found some round head M3 that fit as well.

The simple triangle shape should support most of the spool windings sizes.

This design is deliberately "flimsy", and may need tightening occasionally, I built it to use with the auto change feature of my Prusa MMU2S, I load several of the samples up to print functional parts.

Update... unplanned bonus feature!... specialist filaments fit back in their original baggie so you can keep the data while still on the spool!!!
