Qidi X-One filament spool spacer

thingiverse

I love my Qidi X-One printer but I ran into a problem when using a non-Qidi filaments. The spools I have from 2 makers are 70 mm wide while the one that came with the printer from Qidi is 64 mm. For the direction you need to feed the filament for the Qidi the problem is that when you tighten the spool holder screw the flange will bind the 70 mm spools preventing them from turning. And if you leave the spool fastening screw loose it can self-tighten and bind up anyway all by itself as the printer prints leading to lots of drama, noise, and broken filament. Ask me how I know. Some of the aftermarket spools have an indent that would allow free movement with the screw fastened if they could be flipped to feed the other way, but that is not an option with the extruder feed tube location. Others have no indent and the entire spools are 70 mm. So I made this spacer that extends the length of the spool holder by about 5 mm which is enough to use the "standard" 70 mm filament spools in the orientation required and be able to tighten the holder screw. And the added 5 mm isn't so much that there is any issue running the 64 mm Qidi filament spools.
