A simple button box with a simple and clean, classic, essential design.
I added the carbon film then painted with glossy transparent for a "gloss" effect, but if you have a carbon plate pei it works perfectly.
To develop the hardware i used simhub, really simple. on youtube you can find many videos that explain how fix the arduino pro micro with simhub, sim hub also provides you with the wire diagram.
 

No supports needed
printing with pla/ pla plus or petg
Height: 0.25 for the box and 0.10 for the cover and the frame.

Bolts req:
_(4 pcs)Screws (wooden screws are also fine) M3 x 10/15 mm
_2 or 4 M5 nuts to fix the box in a mount (if you need a personalized mount just write me)
_2 or 4 M5 bolts (about 10 to 20 mm)

you will need a USB cable (Android) to connect to the Arduino, of the length you prefer, but I recommend at least 1.5 meters upwards
