I couldn't find any automatic microchip pet feeder that I liked, so made a fixture to connect two pet feeders:

1. Automatic Pet Feeder by PETKIT.
2. Surefeed Microchip Pet Feeder by Sure Petcare.

The idea is that the dry food dispensed by the automatic feeder will slide down into the microchip feeder through a hole on the lid. The lid can open and close with the slide in place.

If you do decide to give this a try, make sure you train your pets to the microchip feeder with the manufacturer parts first before you rig it up with these fragile 3d printed parts.

All parts are ready to use as printed except the lid part. You'll need to cut off the temporary buttress on the hinge. Then apply little force to break free the hinge joint. No tools required other than a utility knife or a nipper.

Refer to the picture attached for installation setup. Hope this helps someone.
