Yet Another Spool Holder (Wanhao I3)

Clip on spool holder setup for the top rail of Wanhaos and clones. Uses bearings for low friction rolling of spool.

This example; rail and uprights in PLA, 20% infill. Bearings in ABS printed on an Up!

Print the mirror of the upright to get both sides.

Rail is very tight fit, may need to be filed a little, but keeps everything rigid.

Long enough for two spools side by side, or use a dogclip for a single spool.
