I made one and I like it.
There is one mistake in your pcb1.dxf - file. One of the three drill-holes for the screws is misplaced.
Found it after milling, fixed it, milled again and now the probe is probing fantastic ;-)



Thanks for it ! looks great

Can you explain the PCB drawings? Am I correct to assume that the solid black lines are milled completely through whereas the light grey lines are isolation routing on the copper?

Yes, the thick lines are the outline (cut through) and the thinner ones are isolation routing. I did everything with a 1,2mm mill.
The tracks around the holes are there to isolate the screws from the PCB. The two open circles are supposed to create half-islands to make soldering if the wires easier (retains lead from spreading and limits heat transfer)

That is clever to print the whole thing!
