Arduino Gear Clock

This is a gear clock using a 28BYJ-48 motor controlled by Arduino NANO.
Since the operating voltage is 5V, you can use a USB connection or a mobile battery.
Size: width 11cm, height 10cm, depth 5cm~10cm

I was inspired by "Simple Super Gear Clock" by Tokyo_Bird.(Tokyo_Birdさん、ありがとうございます！) So, I made this as my practice.
Also, I used Arduino Nano case by nspohrer. (Thank you, nspohrer!)

(1) To keep the distance between BackFlame and SpurGear60t, spacer was added.
(2) ArduinoGearClock.ino.txt was updated.
(3) sat file was uploaded instead of stl file for over all models.

Although the design need to be improved more, since it could run well, I uploaded this.
You can see how it works in https://youtu.be/wDQAxyr8IB4

I used PLA for large gears and PTEG for small gears, flames and pipe stoppers.
Four pipe stopper are required.
The center hole of gears need to be drilled to
