Neptune 3 Pro - Spool Holder Axis - Long and Thin

Long and thin spool holder spool axis for Elegoo Neptune 3 Pro. It fits the original spool holder thread which is M30.

I had several very old spools of filament that didn't fit on the original Neptune 3 Pro spool holder, so I created a new axis for the spool. This axis is just under 20mm thick.

This can be a direct drop-in replacement or a place for an second spool, as seen in the pictures.

The model is 3D printing optimized, no supports are needed. Recommended orientation for printing is with the threads UP, so you probably want to rotate it upside-down.

I would suggest printing this to be beefy, since it's going to potentially carry more than 1kg or 2lbs of filament. I printed mine out of PLA at 5 perimeters and 50% infill. I ran several destructive tests and it took a lot of effort to break it with my hands.

I will assume that it also fits Neptune 3 Plus and Neptune 3 Max. If anyone tests this please leave a comment.
