  1. Print both pieces in TPU (without supports)
    • Pay attention to cooling and minimum layer time since the little knob at the end of the strap is taller than everything else and heat can be a problem if you print too fast.
  2. Thread the strap through the ring
    • Thread the small T-shaped end into the ring from the outside. It's a tight fit, but it does fit.
  3. Add a couple small drops of cyanoacrylate/superglue and seat the strap all the way into the ring (it's a tight fit, but should fit flush on the inside) – be careful not to pull it all the way through!
    • This glue isn't strictly needed, but it prevents the strap pulling through with rough handling.
  4. Trim the broken leash/strap off of the original lid and clean up the edges
  5. Drill a 4mm or 5/16" hole in the center of the lid
  6. Snap the new leash nub into the new hole (it's also a tight fit, but that's what we want!)
  7. Unscrew the top of the cup, remove the old/broken ring, and add your fresh new one in its place!
