The model from which I made this remix was great, except when installed on the Hero Me Base, the required Hero Me gantry adapter for the Elegoo Neptune 3 Pro lifted the nozzle too high from the build plate. This height difference was so great that the X-axis gantry would bottom out on the Z-axis steppers and the nozzle was still too high to print anything.
The solution to this requires either raising the bed height significantly, which has many drawbacks, or simply extend the hotend further down. So that's what this mount does.
Requires M3 screws and nuts or M3 heat insert pressed into the back side.
Please be sure to calibrate your Z-offset immediately after installing the mount and hotend. Additionally, you may need part cooling fan ducts that are slightly longer to accommodate the added length.

Extended the mounting point further down, lowering the entire hotend in the Hero Me base.
