Small/simple holder for nozzles with M6x1 threads (e.g. E3D V6). Nozzles thread into the holder so no cap is needed.

Works best with E3D V6 nozzles, but should be able to accommodate most nozzles with M6x1 threads.

Recommend printing on a printer that is fairly well tuned, enough to print M6x1 threads. I had good luck at 0.20mm layer height with a 0.40 nozzle. No supports needed.

Optional, print in multi-color to make the text pop more.
