Variable Delrin Wheel Spool Holder

This spool holder uses four delrin v-wheels and is compatible with various sized filament spools. Minimal footprint, ease of production, transportability, and modularity were the major influences behind this design.

Motivation: I needed a larger 1kg spool holder and had plenty of delrin wheels laying around so I made good use of them :P

Two pairs are required - one for each side of the spool.

Additional materials required:
4x Delrin V-Wheels with bearings (mine were from a Tevo Tarantula)
4x M5*25 Screws
4x M5 Nuts
