Controller box / remote / Fernbedienung

Update 2nd of Jan 2021: added a simple txt file with the Arduino sketch code for a modified version with a speed switch

Update: I used these push buttons: https://www.ebay.de/itm/Druck-Taster-Schalter-Push-Button-Switch-12V-24V-220V-2-PIN-10mm-OFF-ON-Mini/184186792241?hash=item2ae2636931:g:1W0AAOSwFctfA3Q2&var=691896065520

and this switch: https://www.reichelt.de/kippschalter-3a-125vac-1x-ein-aus-ms-243-p13146.html?&trstct=pol_14&nbc=1

This is box for a remote controller. There are 2 holes with 10mm diameter and one with 5mm diameter. Also there is a 6mm hole at the front for a cable. Inside the the box the cable can be fixed with a tie wrap. Additionally since I used clear PLA for the upper side of the box I inserted a 5mm LED in an horizontal holder which is part of the box for iluminating the box from inside. Inside the height is 30mm.

I used clear PLA for the first 65 0,2mm layers. The I added a PAUSE command (CURA macro) and continued printing with OWL M-FLAX filament
