Heathkit Signal Tracer Probe Ends

thingiverse

These are the probe ends for the Heathkit Signal Tracer. They both snuggly in my original probe body. The probe cap is for the rear of the and is a different shape than the original. It has 2 holes for RG-174 coax cable which is what I used for the signal and ground leads. The holes may need to be enlarged slightly depending on your brand of coax. The probe tip threads will need to be tapped for the actual metal threaded probe point from the original Heathkit probe. Print this part using support. Both parts will need to be drilled for the small retainer screws using the probe body as a guide. I used PLA filament for these and it worked well.
