Pogo-pin harness to stress-test an electronic module before it gets soldered

Here I am using retractable pogo pins again (see a previous use here), within a little 3D printed harness.

This electronic tool holds modules both quickly and efficiently without any soldering. This way I can test or program them individually before they are eventually soldered on the final board.

Obviously then, things get much harder to debug, and sometimes you do not even have room for ICSP pins to test in-situ, or to re-program a microcontroller.
