Pogo pins
Insert the 10 pogo pins into the nylon connector. Put the pcb on top.
Solder the pins
Applying flux might help. It's all a bit finicky. Nobody said it would be easy. ;-)
If you own a 3D printer, it might help to print a small jig to hold the pins in place. See this stl file
Glue the cap
Don't use cyanoacrylate glue, as this is too liquid: it creeps into the pogo pins, glueing them stuck. Use a simple cheap hobby glue or wood glue. Let it dry overnight.
Done!
