Spool Adapter for Low Friction Adjustable Spool Holder (A1 Mini)

I printed the Low Friction Adjustable Spool Holder for A1 Mini and love it, but I wasn’t happy with how spools with wide holes (e.g., Sunlu) fit. So, I created a simple adapter that solves this! Just screw it onto the spool, and the cones at the ends adjust to the hole automatically. Highly recommend the original design, and now it works even better with this adapter! 

I’ve tested it with both PETG and PLA, and both work great.
