ACE Pro Rear Spool Roller (remix)

This is a remix of "Solution for the Problem of Tangling and Poor Return of Filament in ACE PRO|纵维立方ACE PRO缠料、回料不畅问题解决方案". I believe this will work as good or better. New roller uses the existing bearings in the original rollers. Tap out bearings with the roller rod. I used a "Thwack" hammer that I printed to tap them in the new roller and used a Phillips screw driver to set them in about 1mm. Printed in both PETG and ABS filament. Recommend ABS if using ACE Pro for filament drying.
