That's some nice work.

I didn`t mean short in the diffprobe itself but that the diffprobe, housed in an aluminiumcover and lying around can easily create shorts in the circuit it is probing below.

A conductive case is actually desired to prevent degradation of the AC common mode rejection from variation in the probe's environment.  Plastic enclosures should have a conductive film on the inside.

Will something like the old conductive carbon spray for coating the CRT TV case internal or the CRT tube work ?

I’m definitely interested in placing an order when you think you’re ready for testers.  I have a fair bit of experience designing 3D printable enclosures for OSHW projects and would get to work on that immediately upon receipt of an assembled board.
