K3NG Rotator Controller Case

prusaprinters

Arduino Mega mounts are set for 3m heat press inserts. You might need to trim some of the protruding pins on the bottom of the Arduino, or just remove them mounts entirely in the slicer if don't want them. There's room for a small buck controller and 4 way relay board on one side, and another board the other side. The lid is a tight slide in fit, it will need the corners rounded to stop them catching. I printed it at an angle on the read back corner. The internal support for the top of the Nextion hole required some fixing up mid print, I suggest if you use internal supports they are made a little more substantial.
