Parametric Loom Heddle

Sort of amazed that no one has done this here before. Pretty simple script to make a heddle with any number of warp threads, of any diameter and whatever height. I'm not sure I've calculated the shape correctly as I'm not a weaver and don't have access to people who would know better; if you see a way this can be improved, please let me know. I'm making this to weave a belt, so needed a pretty unusual size.

Update: Now you can select 3D to get a STL file and 2D to get a DFX for laser cutting.

For anyone who wonders:
"A heddle is an integral part of a loom. Each thread in the warp passes through a heddle, which is used to separate the warp threads for the passage of the weft. "
