i3 Mini Spool Holder Mod (Wanhao / Monoprice)
thingiverse
I have some crappy Ebay Special PLA that had a weird spool that didn't slide very well on the stock spool holder, it kept geting bound up. I searched and couldn't find something that would just work so i took inspiration from a few different designs and made this. Each bearing will require 5x 4.5mm BBs. The bearings do fit very snugly on the shaft, they won't ever come back off. I zip tied down the outer support because it kept slipping and hanging up. These can be adjusted for smaller width spools.
