Summary

Wooden Arduino case has place for all basic microcontroller components. The slightly sloped front has room for a 2.4" TFT, has a thumbwheel on the top, inside there is support for Arduino module, perfboard for extensions, LiIon battery, LoRa and Wifi modules, USB charger socket etc.
If you run out of space, just mount the "windybox" on the back, which is also perfect for some gas (CO) sensors, temperature and humidity measurement or power supplies producing much heat.

The case material is 3 mm plywood. On a 40W laser cutter, load the LYZ file. There are two versions of this, one has opening for the 2.4 frame, the other has none. Draw a rectangle for your own display cutout or change the decor layer.

Engrave first the decor layer on 35% power, then remove the decor layer and cut the contour lines two times at 45% power. Glue the front, bottom and sides, leave top and back out for the time being. Build the inside support (glue in the bottom 74x39mm inset the remaining plywood edges) for your needs. Solder the thumbwheel on a small PCB and glue it in place. For all wiring use 10 cm long 0.25mm enamel wires.
The 2.4 " display frame is made for 240x320 SPI Serial TFT Color LCD Module Display ILI9341 with FPC cable. Print the frame and trim the inside edges until the TFT clicks in, no glue necessary.
