Misumi collection: spool holders and NEMA 17 motor holder

thingiverse

I use these http://www.thingiverse.com/thing:545954 rod holders, but they need to fit various universal ball bearing spool holders like http://www.thingiverse.com/thing:124649, http://www.thingiverse.com/thing:127181, http://www.thingiverse.com/thing:173204, and http://www.thingiverse.com/thing:596838. Fancy frictionless ball bearing spool holders often have a problem with filament going off the spool and getting stuck. However, if you've already printed some of these models, you'll need a Misumi holder to make them work properly. That's why I remixed one model that I couldn't find right now, which should provide enough friction for the spools. The only drawback is that it fits 60 mm spools precisely, and they have to be exactly good. Still, it's available if you need it. The nema17 motor holder works well, especially in multiextruder setups.
