Mini Kossel Spool Holder
Yes, yet another spool holder for the Mini Kossel. I found a lot of examples I liked but none were exactly what I wanted. The one that came closest was http://www.thingiverse.com/thing:312624.
This one uses the 50mm roller from http://www.thingiverse.com/thing:119016 (but you can change the size to fit your spools.
This is designed for the 15x15 OpenBeam frame but you can modify it to fit your frame.
