Xvico X3 Spool Holder

thingiverse

The Xvico X3 is an Ender 3 clone, with a spool holder on top. However it's just a bent bit of metal, and the friction means that the feed is uneven. This build has two end-caps which fit over the existing spool holder, which allow you to mount a piece of 8mm threaded bar (about 100mm long). There's also a tube with a mount for two 608 bearings, which will go on the bar for a super smooth feed. A couple of bolts and a large washer keep everything in place. For the X1, just use the tube, and add large washer to make sure the spool doesn't fall off the end. It really helps, as the X1 doesn't have the greatest filament path. I've updated to add a little extra height to the larger block. This prevents the roller riding up onto it, which occasionally caused minor snags. A washer would do the same but space is a little tight.
