Watch Strap Loop for Swatch and maybe others

cults3d

This design fits a Swatch watch strap but could also work for other watches. Two versions exist: loop1 has internal dimensions of 17x3.5mm and 1.2mm wall thickness, while loop2 is slightly smaller at 17x3.4mm with 0.8mm walls. I opted for the second version with thinner walls. To install the loop, a metal pin was used to push out the retaining pin, allowing the strap to be removed and then reassembled around the new loop.
