This is a must have for cardboard spools. We need the plastic on plastic contact for keeping a low load on the extruder. This also stopped my spool from “drifting” off my holder! Thanks! (edited)
I was really bummed out when I got some new filament and found there to be feed problems on my MK4 due to the incredible friction between the cardboard spool and the stock spool holder. While babysitting my first print (which has artifacts from the feed issue) I knew I had to make some of these and wanted to check Printables first before going through the effort of making them.
I definitely prefer the second version of the model for how much better it holds the spool. Thank you for sharing and saving me some time!
