I ordered this part in PETG. When it arrived it was clearly printed in PLA. I've attempted to contact the maker and have not received any help. It took a few days for them to respond. They claimed that the part is printed in PETG but it's clear to me that this is not the case.
First I ordered one ring as a test because I wasn't sure it would even work the way I wanted to (it's to keep my cats from opening their timed dishes). It worked perfectly so I ordered three more! For the first time in a long time, the cats can no longer crack open their evening meal early (and then start loudly complaining about breakfast at some ungodly hour!)
Yes, my cats figured out how to hook the dial with their claws and advance them to open the dishes early.
