    That center pin looks fragile, especially if it's printed along Z axis. How about printing teeth that'd mesh with the belt?

      Printed teeth are weaker than the belt's own teeth.

      Conversely, with this design the center pin could break loose and the belt would still hold, because the pin just has to stop the loop from fitting through the slot.

        The pin doesn't even need to be captive, if you tug on the belt it'll jam in the slot kind of like a climbing nut in a crack.
