I wanted to encapsulate everything I needed to print manually standing at the printer with a touchscreen, and upload files over wifi. I built this idea around my cheapo TronXY X-1 to make a an easily portable unit. This was the result.

This case has space to hold the stock TronXY 12V supply, a Mega2560 with RAMPS, an RPi 3B+ with a 3.5" touchscreen, an extra 40mm cooling fan, and an IEC socket with power switch.

The touchscreen used is a generic 3.5" LCD with the XPT2046 touch controller. This communicates through the GPIO pins not HDMI. The RPi is running OctoPrint with OctoDash as the touchscreen interface.

The IEC socket is an inexpensive, unfused model from a long time ago, so you may need to adjust the cutout to match your unit.
