Cardboard Spool Rim - PolyTerra, PolyLite, Universal

I wanted a rim for my Polymaker cardboard spools that were less flimsy, while keeping room for the silica holders and easy to remove. There are files for Polymaker PolyTerra and PolyLite with tabs for the holes in the spools. *The PolyTerra files are for the newer spools that have the larger holes. There are also Universal files that don't have any pegs and should fit a wide variety spools. The standard versions are smooth and work as intended. If you need more traction there are ribbed versions as well. Depending on your AMS, the lid may or may not close. To fix this, print the improved rear rollers that will give you a couple more mm of clearance.
