Holder for a LD2410B module

Slot-in construction for the LD2410B (should also work with the non-B model) module so that you can put it onto some metal base (space for a disc-magnet 6x2mm in the bottom part).

Detection works through the printed material. 

No further fixation needed. Should be a tight fit.
Also a small gap for feeding out the cable is added.

Depending on the accuracy of the printer you might need to re-print it with 10x% or more better fit.
