Overall I’m very pleased with this print. Works as described with rudimentary seesaw action so two are up while two are down. I included a couple of photos of the mechanics so others can assemble easier. I was unable to find any assembly instructions anywhere and the patron link is erroring out. I do wish all of the spare feed trays would fit inside the unit for storage. if you print them all, one has to be in use and one does not fit inside. You do have to glue in the beauty rings around the “beans” and if those were expanded to snap in the entire print would be glue free. This is fun and I’m sure the new kitten will enjoy it!
