Neptune 4 Spool holder adaptor

This adaptor allows you to move the spool holder from your Neptune 4 (and probably 3? Please let me know!) off the top of the printer and mount it to a wall, or in my case to a board to sit beside the printer. This should improve vibration due to the removed mass and make your input shaping more consistent (no changes in mass as the roll is used up). Printed a second spool holder to have two rolls on at the same time.

Printed in PLA+ with 4 walls and 25% infill. Use whatever 3-4mm wood or machine screws you have to hand.

I've added the Bowden tube adaptor bracket I used to allow the filament to feed into the extruder here:
