threaded through hole with slot

thingiverse

I made this for a heated drybox for the heater, but it should work with any standard 2 conductor electrical wire. Threaded parts designed for a 20mm hole, but flange should work with up to a 26mm hole. Has a slot in both parts to allow you to place over a wire without having to cut ends to get wire through. Might recommend an oil or lubricant on back nut as it can be a little tough to thread dry, but once its tightened down it is not going anywhere.
