The backlight bulb for my climate control panel burned out. I needed a "radio removal tool" to release the control panel from the console.

These keys will "unlock" the latches holding the radio to the console.

This was quickly put together based on a picture at benzworld.org/forums/w210-e-class/1514205-tool-key-pull-out-radio-unit.html

Loosely modelled after a Mercerdes Unimog

Printed mine on an Ultimaker in about 11 hrs total.
The bed lever leaves something to be desired, it's not quite working as I'd hoped.
All STL's have been dimensioned so as to account for the oversize that my Ultimaker/gcode-generator produces (ca. 0.2mm around the perimeter).

Mine runs smoothly, images are to follow.
Have fun !
