This has two MAJOR benefits over the stock spool arm.

1. Has a smaller diameter allowing you to use smaller .25kg spools (see photos). Works great on standard size spools too!
2. Has an integrated Buffer Guide for the PTFE tube. Helps control the alignment of the tube while protecting it when not in use.

Simple print. UseS the screws from the stock spool arm. The end cap is a friction fit, but I do recommend CA glue to secure it in place.
