Made special shuttle to match 40 cm wide table loom (self made with a lot of 3-d printed parts, see pictures).
The pin made from 2 mm welding wire (euro 0,49 per meter), drill the hole for the hingepin to 2 mm and use small lenght of same welding wire. Cutting with Dremel is easy.
Print topside down without supports. Brim advised for good adhesion. Took me 7 hours to print on 0,2 mm layerhight, 50 mm/sec printspeed.
