Small Dosage Automatic Fish Feeder
thingiverse
Modified version from [pefozzy's design](https://www.thingiverse.com/thing:2539750) (base, arm reference design) and [MarcDuGard's design](https://www.thingiverse.com/thing:3008139) (bowl), adapted for a smaller dosage size. The dispensing hole is 4mm in diameter, which is roughly 3 betta pellets - sometimes 2, sometimes 4. This is about right for my tank. More or less any servo should work - I'm a 55g 40x20mm servo since they were readily cheap + available + metal gearbox. [code here](https://github.com/williamtdr/fishsrv)
