In the last couple of months I've done some modifications to my 3D printer. First thing I added was a LCD with rotary encoder, having the printer attached to my laptop, which was not very convenient since prints can take hours and I only have only laptop. To mount the LCD I used my CNC to mill a small housing that fit on the front of the printer. To finish this off I added some switches to for the LEDs and fans and used my laser to etch some text.
