fish feeder

https://youtu.be/L19q9VMS01A This is a little project I've been working on lately. It's indeed an automatic fish feeder. The goal was simple: create a consistent and easy-to-print feeder. After a few iterations, I can finally say that I have a working model. All parts print without supports and complexity is kept to a minimum. To build this feeder, I made a build video and the required parts are listed below. Make sure to print the tolerance test first because every printer is unique and your parts might not fit perfectly together. The two parts should fit really snug (almost a press fitting). For the Arduino, I used a case by hakui033: https://www.thingiverse.com/thing:1441839 By the way, I know that I shouldn't power the servo directly from the Arduino, but this is temporary. I'm not an expert in Arduino coding, but I managed to create 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 bolt head 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
