Here's a solution I came up with, might be useful for some of you. This mod can be (and was) entirely done with hand tools. It also might help with the consistency of temperature readings.

Parts required:

  • M3x5 Screw*

  • M3 or #6 washer

  • Thermal paste

*I didn't have one this short, so I just filed down a longer one

Tools required:

  • Marker

  • M3 Tap

  • 2.5mm (or equivalent imperial) drill bit

  • Drill

  • Tapping tool

  • Clamp

Steps:

  1. Line up the washer on the side of the nozzle so that one edge completely covers the hole made for the thermistor. Mark the center.

  2. Clamp down the nozzle, and using the 2.5mm bit: drill a 6mm deep hole in the edge of the nozzle where you marked the center of the washer.

  3. Carefully tap the hole using the M3 tap and tapping tool.

At this point it you should have this:

Installation:

  1. Apply thermal paste to the thermocouple, and insert the thermocouple into it's hole.

  2. Cover the thermocouple with the washer, and clamp it down by tightening the M3 screw.

That's it, you should have this:

That extra hole you see shouldn't be there, I made a mistake when drilling yikes


Let me know what you think. I believe this is the same method e3D extruders initially used for their thermistors.
