This is a drop-in replacement for the mechanical ice cube system Siemens 00709709 (which is a very bad design prone to breaking, jamming and with low capacity).
Add plastic drawer 44-4173 from Clas-Ohlson and a regular ice tray on top. Easier to use and better capacity.
I printed mine by cutting it up and adding dowels in order to fit my MINI's build plate.
FreeCAD model available for the brave.
The author marked this model as their own original creation.
