Chinese Leather Shoe Patcher foot

Taking inspiration (but building from scratch) from Stoubian's zipper foot - this foot allows much closer alignment of a guide - meaning straight stitch lines as close as 2.5mm from an edge.

Version 13 is updated with reduced stress risers and I've been printing in ABS with 50-75% infill. Old version could snap if brought down too hard on the armature, the new version is bombproof!

Print on it's back, no support needed.
