This end-cap will protect the USB Type-C connector on the TS80P soldering iron from mechanical stress. It is still possible to remove the plug but it can not moved sideways.
Important:
Designed for the original silicone cable of the TS80P
The dimension of the part that is put over the end of the iron is 13mm; exactly as the iron itself. Because holes tend to get smaller when printed, you need to experiment to get the tight fit required for stability. I printed mine with a scale factor of 1.0125 and cleaned the inside of the hole with a knife. For test-prints, move the part 15mm down into the build plate to waste less material and time.
