This is a remix of "Bear Y belt adapter for MK2s/MK2.5 on Bear MK3 frame". https://www.thingiverse.com/thing:3468567
My Y-axis belt from the MK2 was too short, so I modified the belt adapter to require less belt for fastening. I'm not a Fusion 360 pro user, so this part is a "works for me" mod.
Belt path is fairly good, but not 100 % perfect.
