LCD2004 Arduino Nano 328P Mod. (Upgrade Cover Kit)
thingiverse
I search for a suitable position to place my Arduino Nano close to the switch. I use the ATmega 328P to control my printers lighting system https://www.thingiverse.com/thing:3086797 independent from the main control (operating with Mega 2560). https://www.thingiverse.com/thing:2475882 The Nano is fixed with 3x M1.6 screws below the cover part. Optionally you can fix the Nano with 4 screws (i avoid to reduce stress). By unclipping the side covers you can easy access the USB connector to upload Marlin software. I used a simple Lego Lasersword to extend the Main Status LED to make it visible during printers operation.
