Lid Lock (for PETLIBRO Automatic Cat Feeder)

Billy is smart.But he is too smart… he figured how to open the lid of the auto feeder and help himself an “All you can eat” meal. The Vet said, no, Billy is overweight already, he have to control the weight. So I printed this simple lock for the lid, its only cost 8g of the plastic you choose and 15mins to print. And the best thing is, it works! Billy is looking outside while im posting this. He must be thinking how to open the lock now.
