My dog tends to entangle himself in our segmented curtain so sometimes the cips fall off and are nowhere to be found. I designed replacement parts because the company who built the system told me they were unable to provide replacement parts.
This is an easy print if you have a nozzle
Print the outer walls slowly, if your printer tends to produce bulging corners. That might help to get the measurements in check.
After printing just snap off the built in support rods and clean up the clip a little bit. Should work fine then.
