This is just a quick mount for a BIQU H2V2 hotend on an Elegoo Neptune 2.

The mounting holes don’t really line up a simple manner so I made this side arms that attach with some heat set inserts. When it’s all tightened down it’s rigid but I’m nevertheless having some issues with this the nozzle of this printer lifting up a fraction of a millimeter when it pulls in the filament and dropping back down on z retraction.

That should be solvable with some additional z-hop in the slicer and perhaps a bowden tube the lifting force to the frame of the printer.
