Up Mini Spool Holder (using 608 Bearings)

This is my version of a Spool holder for my UP! Mini. I found some spools were catching on some of the other Spool holders I had printed for different sizes, so I designed this one to use a roller supported by 2x 608Z Ball Bearings (Standard Skateboard Bearings)

I have also slightly tapered the Roller to try and ensure the spool sits as close the printer as possible. Make sure you take note of this when you assemble.

To install the Roller into the Holder, I used a Heat gun to slightly soften the end so I could fit it in and then push the Axle back in.
Works a treat !
