Brass Nozzle, 0.4mm, for Standard Prints
This is the default JellyBOX nozzle. It's reasonably fast, and retains good amount of detail.
Nozzles with 0.4mm orifice are the de-facto default in all FFF 3D printing. Brass has low friction and good thermal conductivity, making it a great nozzle material.
However, brass is quite soft and wears out, so you need to replace your nozzle to maintain peak performance. Thankfully, these are relatively cheap.
