LCD and switch holder for a BigBox printer

This is a special ad-don for a BigBox (Dual or Pro) printer. Since the case-fan always runs on 100% and makes a lot of noise, I decided to control the fan with an Arduino via PWM. The setup is simple: I measure the in-going and out-going air temperature. If the difference exceeds a certain level, I increase the speed of the case-fan via a PID regulator.

The print holds a standard LCD (I2C) screen (1602) and two buttons with a hole size of 15mm.
