Duck feeder

thingiverse

3D printed duck food dispenser. Uses a bottle as a food container. Other parts: 6x m3 20mm bolts and nuts, 4x m4 20mm bolt, 1x m4 nut, some thread lock glue (superglue would do) for the screw used as the main gear shaft, wires for the motor, Arduino (or ESP32 or another microcontroller) with a motor driver IC for control. Motor: https://www.amazon.com/gp/product/B083BDW3FD/ I printed it in PLA (for getting the dimensions correct), when/if it fails I'll re-print in PETG. To avoid jamming, my code runs the motor in alternating direction each time. I dump a bit of food on random intervals, hoping that it'll get the duck to mainly hang out by the dispenser. The openscad code depends on: OpenSCAD gear generator, The Belfry OpenScad Library, v2
