Inland Filament Spindle insert (Microcenter Filament)

thingiverse

I picked up some affordable filament from Microcenter, but the spindle's dimensions were completely off, with a center hole that was way oversized and wouldn't fit snugly in my spindle holder. Every time I moved it, it made a loud noise due to its tendency to rock back and forth. To get around this issue, I decided to create a makeshift adapter so I could keep printing without any interruptions. This project requires two standard 22mm outside diameter skateboard bearings, although you might be able to skip them altogether and use a rod instead. As it happens, I have a passion for crafting big, satisfying threads, which is why this design features several of them. Since I'm paying $15 per kilogram for plastic, I didn't feel too bad about making this adapter a bit more substantial than necessary. Right now, I'm working on building a custom spindle holder that's specifically tailored to accommodate this unusual spindle size.
