Mini Spool Holder for EIBOS Easdry and Polymaker Spools

This is a remix of https://www.thingiverse.com/thing:5673843

I found that the Polymaker cardboard spools take up almost the whole width of the Easdry and the original design would not work with them. This remix moves the bearings all the way out and coincidentally removes the need for screws. Make 2. Bearings push on.

Use 4 × F688ZZ bearings
