I have recently taken up the hobby of 3D printing. I have experienced many issues, but not one that I could not solve such as this yet. I have a heating block that has a hole for a thermistor that is threaded in M4. My thermistor is threaded in M3. I have searched the internet for some sort of thread adapter that I could screw my thermistor into, then screw into the heating block, but I have had no success. I have also tried to just stick it in with a mixture of thermal paste and super glue, but it also was unsuccessful. If anybody could shine some light on my situation, that would be amazing!
