ACE Pro High Efficiency Back Pulley - Slim

Remix of bedriddendesign's ACE Pro High Efficiency Back Pulley. Some spools of filament are a little bit larger, and when using the High Efficiency Pulley, it would interfere with closing the ACE unit. This just slims out the middle a bit to allow the ACE to close better. This still uses the same 693zz bearings as the original model. https://www.amazon.com/dp/B07FVYPMPX?ref=ppx_yo2ov_dt_b_fed_asin_title.
