This model is a revisitation of the central block of the project -Philips HUE 1U Rack Mount ( https://www.thingiverse.com/thing:6022481 ) -
I completely redesigned the central part for a Waveshare 1.5inch RGB OLED display and a support for an esp32 development board (ESP32-DevKitC-32 ESP-WROOM-32 https://it.aliexpress.com/item/1005004435118716.html?spm=a2g0o.order_list.order_list_main.56.6cae3696NtwMG8&gatewayAdapt=glo2ita )
