Shorter chain adapter for crab (BMG)

thingiverse

The original mount for this chain ended up making the chain go in a weird curve. Tried making the whole thing shorter, ended up with 2 different designs. I chose the lite version. Other changes: - The huge cutout was replaced with a groove (2 variants) - Returned some wall pieces that were removed in the original, as they play some role in keeping the clip in place - Lite version that doesn't have any excess plastic on the base plate, and even removes the hole that doesn't get a screw on the original. UPD: Added a variant of Lite version for flush head screws. NOTE: requires a replacement for standard screws in the feeder. The optimal choice is 45mm M3 flush head screws, but I added versions for standard head screws as well.
