Timing Belts with back slots
thingiverse
Add HTD 3 profile and back slot for strength. The drive belt was made from Grillon Nylon 12, an excellent material that is even more taut than Nylon 6 from the same manufacturer. However, I believe it's entirely possible to make them in Flex, Nylon 6 or Nylon 12. The issue with printed belts is that they don't have a backPlain, which is the fabric or thread behind that provides rigidity and timing teeth. I changed the SCAD sheets for corread so now you can have some channels where a polyester multifilament thread (like common drive belts) or fishing line could pass through. Once the material has passed through, it's completed with a layer of SupraBond transparent adhesive or silicone to ensure any shedding is prevented.
