Threaded probe holder?

[kris2001]

I got a plan for 3D printed probe holder but how do we put grooves or threads so that plastic screws can go in and tighten?
Thx

A tap.

EDIT... ^ is correct.... you can TAP it. If you don't have the holes.

Otherwise if its part of the file...
You just need to make sure you have the proper orientation so your printer wont barf on the threads.

But to be honest, i don't even use the nylon screw, i just drop it in, unless the hole is too large for the probe to completely slip though.

I print mine then chase the threads.
