Giant LED clock

I designed this big clock (72cm high) based on several existing designs (https://www.thingiverse.com/thing:5392225, https://www.thingiverse.com/thing:5233126).
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
