3D model description

I designed this big clock (72cm high) based on several existing designs (,
The diameter is driven by the use of a 60 WS2812B led strip of 30 leds per meter.
The ring is composed of 12 segments (10 regular segments, 1 right support segment and 1 left support segment) to be glued together and secured with 12 M5x20 bolts (to be mounted with Nut1 and Nut2 pieces). A link piece can be glued between two adjacent segments to secure the gluing.
The ring is attached to the Base with 4 M5x20 bolts.
The number parts are printed in white for the 4 first layers, then in black after a filament change. Layer height 0.2mm
Once the led strip is installed, install 60 Wall pieces and the 12 Number pieces.
The clock is controlled by a D1Mini ESP 32 controller mounted in the Base with the Arduino piece.
Led signal is connected to pin 4.
For now, I used only 2 push buttons to control the background light (connected to pin 16 and 17).

The parts I used :
Charger 5V 3A
Connector 5.5x2.5
LED Black PCB, 2M 30 IP30
Push buttons

Update 08/09/022:
I have uploaded a second version for arduino code (LED_ring_V02.ino)
The third puss button (connected to pin 12) is used to toggle between 10 background light modes.
The fourth push button (connected to pin 32) is used to switch ON and OFF the background light.
