fish feeder

https://youtu.be/L19q9VMS01A This is a little project i've been working on recently. It is indeed an automatic fish feeder. The goal was simple, make a consistent and easy to print feeder. After a few generations I can finally say that I have a working model. All parts print without supports and complexity is kept to a minimum. In order to build this feeder I've made a build video and the parts needed are listed below. Make sure to print the tolerance test first because every printer is unique and your parts might not fit properly. The 2 parts should fit really snug (almost a press fitting) For the arduino I used a case by hakui033: https://www.thingiverse.com/thing:1441839 Btw I know that I shouldn't power the servo directly of the arduino, but this is temporary. I am not an expert in arduino coding but I managed to make a really simple program. Feel free to make a better program and if you do let me know ;) program (put a # before include): include < Servo.h > Servo myservo; int pos = 0; void setup() { myservo.attach(9); } void loop() { myservo.write(85); delay(2000); myservo.write(90); delay(86400000); } Parts to buy: arduino uno r3 2x M4x10 bolt 2x M5x10 bolt 2x M5x16 bolt (max bolthead height up to 3.2 mm) 2x M5x20 bolt 2x M4 nut 2x M5 nut 360° servo: https://www.aliexpress.com/item/360-Continuous-Rotation-Servo-Steering-Gear-360-Degrees-Servo-Dc-Gear-Motor/32474164271.html?spm=a2g0s.9042311.0.0.20ed4c4dwO5Ihv
