Spool Roller for Ender 3 S1

This is a remix of sdbruder's Filament Spool Holder: (https://www.thingiverse.com/thing:5233543?collect)

I wanted to improve two items on his original design:
1. Use roller bearings for smooth feeding.
2. Eliminate need to disassemble to change filament rolls.

This simply sits on a shaft with a collar to keep the spool on, similar to the OEM mount (but it rolls!).

You will need 2 25x37x7mm 6805N 2RS Ball Bearings along with the 3 printed parts.
