Nozzle replacements

I didn’t notice (maybe missed the link) for a replacement nozzle for my Taz 6 single extruder. What is recommended for 0.5? I think my tool head is newer so the nozzle can be replaced?

If you have a Single Extruder v2.1 on your TAZ 6 then you want a Hexagon nozzle. See

I see the replacements “Micro Swiss Wear” which looks like my older tool head but my newer tool head has a six sided that look similar to the E3D styles I see. Which is correct for the newer version?
Also are there instructions somewhere for replacing the nozzle? Just hold the block with one wrench and unscrew the nozzle with the other? Righty tighty/lefty loosey?

I think this is what you are looking for…
