In this project i use 113 LEDs ws2812b, arduino pro mini, micro sd card module, RTC DS1307 time module with DS18B20 temperature sensor, ir receiver vs1838, photoresistor, buzzer with IRL540N MOSFET and step up transformer. To power the watch I used an old laptop charger (19v, 4.5a) with a step down transformer - XL4015.

I used m3 (about 7mm) screws to connect the segments, you can use glue. If you want to assemble the whole clock, you need to print: -20 pieces called: "clockClassic.stl" -4 pieces called: "clockMiddle.stl" -2 pieces called: "clockClassicV2.stl" -2 pieces called: "clockClassicV3.stl" -24 pieces called: "clockClassicCase.stl" -4 pieces called: "clockMiddleCase.stl" -1 piece called: "clockBarR.stl" or "clockBarRV2.stl" -1 piece called: "clockBarL.stl" -1 piece called: "clockBarLcase.stl" -1 piece called: "clockBarRcase.stl" -1 piece called: "alarmIzolation.stl" (you should put it inside part named: "clockBarRcase.stl")

Not required: -1 piece called: "stepDown.stl" -1 piece called: "stepDownCase.stl" I used these parts to hide the step down transformer.

I used about 0,26 kg black filament and 0,135 kg white filament to print everything.
