Cardboard Spool Insert (ERYONE Branded Cardboard Spools)

I created this after having Cardboard Spools having drag issues on one of my printers causing under extrusion and jagging. A quick simple print out of PLA or ABS, clip in into the spool and have smooth rolling for the spool. When finished, unclip it and place it in the next cardboard spool, keeping with the low environmental impact theme of cardboard spools. May work with other brand filaments cardboard spools as well.
