The file 'Misumi Collection: Spool Holders And NEMA 17 Motor Holder 3D Printer Model' is (stl) file type, size is 241.2KB.
These are 3 things: spool holder for 60 mm filament spools, rod holder for universal ball bearing spool holders and nema17 motor holder for bowden setup.
So rod holders. I use these http://www.thingiverse.com/thing:545954
But it should fit to http://www.thingiverse.com/thing:124649, http://www.thingiverse.com/thing:127181, http://www.thingiverse.com/thing:173204, http://www.thingiverse.com/thing:596838. Generally I think that fancy frictionless ball bearing spool holders are not so good because filament goes off from the spool and stuck. But anyway if you printed some of these you need Misumi holder.
Thats why i remixed one thing that i cannot find right now. That should have enough friction. But it fits only 60 mm spools and they should be precisely good. Anyway you have it.
And motor holder is ok, use it, especially with multiextruder setup.
