Neptune 4 (Pro) fillament guide

For when you have multiple spools installed on your printer.

The print simply clips onto the top rail of the printer, and you can feed the filament trough.

Printed with 0.28mm layer height, and 35% infill. (less is probably sufficient)

Keep in mind that you will need to disable the fulfillment run-out sensor, or keep another spool in it for the printer to work. May cause too much friction on taller prints. (>180mm).
