Automatic small pet (hamster) feeder designed to be used with Tuya compatible Touchcube II Zigbee programable button.
Idea is to be able to remotely once to pour feeds from above the cage.

Things assebled from four parts. Main body and cover plate (moving part of the feeder) to be printed.
And Touchcube with longest accesory (the one with hook, not default small arm).
Cover plate has small tooth to be removed to fit plate in exact position needed. My setting is to remove all except the very last.
This configuration will made feeder permanently open once used. You may leave few more and then it will be able also to close the door back.
