Top Spool Holder for Core One, Modified to use 608zz Bearings

Update V2.  I changed the angle of the roller to be more stable.

I combined the model from Prusa with and old model I got off of Thingiverse that uses 608zz bearings to reduce friction caused by the cardboard spools.  It's probably not necessary for most applications, but printing TPU85 in the CoreOne, I wanted to reduce friction as much as possible as it is very temperamental with softer TPU.

To use this with the CoreOne I Used https://www.printables.com/model/1429641-msk4s-spool-holder-adapter-to-top-spool-holder-on to mount it.

You will need 2ea 608zz bearings in addition to the printed parts

Printed with supports as oriented.  Supports under the bottom of the roller and at the top/inside of the holder.

.20 layer height

15% Infill

I used PETG, but PLA should be ok.

Replaced Static arm with roller using 608zz bearings
