Printhead HGX Lite + Volcano for Neptune 3 Pro/Plus/Max

I made this model to replace the original printhead. The nozzle is located exactly in the same place as in the original printhead, so there is no loss of print area along any of the axes.
The mounting of the original Z offset sensor is not provided. Use a separate mount bracket with Cartographer 3D probe, it is much better. And of course your printer should be switched to Klipper.

Before assembling this model, carefully review the photos, as they contain important information.
