Pogo pin tester

I was inspired by the PCB workstation project on https://www.thingiverse.com/thing:2318886 to make a precise test probe holder which uses pogo pins. The target was to test 0201 components so I needed precise, reliable and easy to get spring loaded contacts and pogo pins seem the best choice for this. You can get pogo pins from many places but I used Farnell ones:
