UM2 Clone Spool Holder Assembly

Update 5-JUN-2018: I added a new clamp/clip see https://www.thingiverse.com/thing:2948086

The holder itself is a double bearing remix of https://www.thingiverse.com/thing:767317. I originally designed this for the Anet A8, but I didn’t see the point of publishing it as a remix when there were already over 200. My remix uses two bearings on each side of the spool. I also remixed the small clip that keeps the holder in place by adding threads. The original version of the clip would slide along the threaded rod when the spool was full/heavy.

The clip should be printed at 100% fill. I printed the holder and A-frame at 50% fill, and support - touching build plate. (You could probably print the holder at 20%)

I’ve included a bearing fit test STL. Because it takes quite a while to print the holders, print the fit test before printing the holder to verify that the bearing will fit snugly. If it doesn’t fit, try scaling till you get a good fit (and then scale the holder).
