I'm tired of the involved procedure of nozzle swapping. Nozzles should be:
1. Swapped cold (without heating to 285 like some printers require.
2. Do not require awkward rotation of parts during installation.
3. Install repeatably at the same height.
Here is an idea of how to do it.
The nozzle is made of a rectangular brass block. The cylinder at the top of the block has thread on it, and the nut presses the heatbreak to the nozzle. There should be no need to hot-tighten the nut.
The conical hole in the center of the nozzle serves to clamp it to the heater block using a screw with a matching conical tip (not shown).
If plastic is retracted, the nozzle shoud be able to just detach from the heat break.
I don't have time to pursue developing this idea, so putting it out in the open, with a free license to use to whoever finds it useful.
