Line Splice Sewing Machine Presser Feet

These are presser feet designed to fit many sewing machines for splicing pieces of line to create eyelets, especially useful for example in paragliding or kiting.

I've designed around low and high shank machines that I own, namely Pfaff 360 (low shank, also used as example for the photo), Pfaff 1071 (low shank, IDT) and Pfaff 1229 (high shank, IDT). To determine whether you own a low or high shank machine I assume it's easiest to measure the total height of a presser foot + attachment. If it's somewhere around 20 mm it's low shank and around 30 mm it's high shank.

I print them lying on the side from PLA with standard settings and variable layer height. See sample plate file attached or refer to photo for orientation.
