(WIP) Elegoo Neptune 3 LGX Lite Adapter

I wanted to make my Neptune 3 direct drive but keep things as light as possible. So I got an LGX Lite and made this!

An Adapter to fit a Bondtech LGX Lite to the hotend setup of the Neptune 3. 

Works with both the stock hotend, and the revo voron mod from Ray ( https://www.printables.com/model/262796-e3d-revo-adaptor-for-neptune-3 ).
 

Depending on which hotend you use (revo or stock), you might have to adjust the lengths of the bowden tubes involved with your hotend. I didn't get measurements because i forgot to. But you only need to take a few mm off the tube going into the hotend. And you'll need a second tube that goes from the lgx down into the hotend. If you get the fit right, the filament path will be seamless.


Screw the LGX into the part first, then it kind of just slides down and over the hotend and has a cutout for the wires on the left.

You'll need 3 m3x6 screws and one m3x12 to mount the bondtech to the part. And you'll also need 2 m3x12 screws to mount the part to the hotend shroud.

Long term plans include adding strain relief for the cables and making the mount even lighter.

Step file included so anyone can improve upon my crappy engineering.
