Found and restored a VTVM (vacuum tube volt meter) which was missing the probe. Obviously I printed my own, being that we're on this site.
The coax is RG-58C/U and the heat shrink is for a 18650 lithium ion battery. I had the probe tip off an old volt meter. I used some more heat shrink(not shown) for the coax to provide extra strain relief, and a bit of extra protection since the VTVM is rated to 1500V.
You will probably have to play with the clearance in the taper to get the inside
