Cat feeder for wet food

thingiverse

This is a semi-automatic cat-feeder which I integrated via an ESP8266 (Wemos D1 clone) into Home-Assistant and is meant to be used with wet food (also everything else will work just fine too). You can prepare the meals into the bowls, close the lid, lock it and open it at any time you want via Home Assistant (or anything else). It's a tight seal, so it's not getting dryed out over some hours. On the bottom is a small drawer for some Ice-Pack so the food is getting cooled a little (neither printed, nor tested so far). All you need: 1) MG90S Servo-Motor. SG90 should also work. https://www.amazon.de/dp/B086V8RKZR 2) Round rubbergasket with 5mm diameter https://www.amazon.de/dp/B077MZVCYC 3) Bowl with 140mm outer diameter and around 35mm height https://www.amazon.de/dp/B08TGM24H1 4) Springs for the lid https://www.amazon.de/dp/B09Z2JX821 5) Controller-Board depending of your use-case (Arduino, ESP8266, ...) 6) A micro-button. Mine are the one from the Set bellow with 6mm length on the edge. https://www.amazon.de/dp/B09QM56YHL 7) M3-Screws for the axle and to screw the front-cover into the body) 4 x 6-10mm 2 x > 15mm (axle) 8) (Optional) Ice-Pack with ca. 150 x 80 x 20mm 9) (Optional) Hall-Sensor + Magnet (8mm diameter x 3mm height) 10) Superglue and hotglue Printing: What you need to print: - bowl_body - bowl_front - bowl_top - bowl_lid - bowl_lid_closure Only the lid needs to be printed with supports from build-plate only. Even without supports you only need to cut a little part (tryed this by mistake...), but I would recommend to print the lid with supports. The plate (optional) should be printed mirrored, so the "smooth" side shows downwards. This is just for better cleaning, so you can just take the plate, clean it and put it back on.
