Work in progress, don't expect this to work without modification 

Post a comment if you see a better way to do this. The idea is to spread friction across the entire surface of the spool so it doesn’t saw through the PLA as quickly. With the current iteration I’m having trouble with the spool vibrating at high speeds

To do:

• Print and test with
  • Cardboard
  • Ribbed plastic
  • 2 KG plastic
  • 3 KG cardboard
