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.
