This is a simple panel mounting for a Mitsubishi FR-DU07 "Parameter Unit" / control unit for Mitsubishi FR-A700/F700 series transistorized inverters (frequency converters). It allows remote control of a single Converter from operators' panel.

The main body is printed in ABS of 2 parts, glued by acetone. Don't forget to take into account 0.3%...1.5% thermal shrinking, according to your material! The RJ-45 connector together with a piece of PCB is cut from an old Ethernet card, then drilled the mounting hole.

The whole device is installed in ~ 84x54 mm hole in a metal panel. Works fine :-) .
