Top and Bottom work in progress.
Fit 25 esp32 boards in a row, but recommend only 12 with a fan as there is a heat increase with all these boards so close.
I ran it for a few hours without any air flow and it got pretty hot, so i needed an 80mm fan
2mm slot gap for each board.
Duino Coin logo on side of box.
Working in improved lid connection
Built on ESP32 board (not welded)
