Automatic Microchip Pet Feeder with Back Cover

My cats figured out how to get into the back of the Surefeed to scoop food out of the hole in the lid with their paws, so I had to figure out how to fit the back cover onto the Surefeed without blocking the chute opening of the Petkit feeder.

I dremeled a hole in the back cover of the Surefeed to accommodate the chute. Then I remixed the bridge and the chute to account for a longer distance between the two feeders, and added a quick scaffold to hold up the longer chute. It's not the prettiest scaffold, but it works!
