Qidi X-Maker Spool Holder Upgrade

thingiverse

I was let down by Qidi's "baggage handle" spool holder because it generates a lot of friction that causes inconsistent extrusion, particularly with flexible filaments. A swift trip to Tinkercad and we have a solution ready! It requires two (total) 608-sized ball bearings; I've used 608-2RS. The tolerances are extremely tight, so you may want to print the inner part first, check if your BB fits, and adjust accordingly. I printed mine at 102%, just to compensate for ABS shrinkage. No supports needed whatsoever!
