UP Plus 2 Feed Guide
Been using it for a while, seems to work well enough. Printed ok as positioned in file, 0.3mm layers and medium fill. If you push hard enough you can break the centre leg when you clip the feeder on.. use a filament that is more pliable. no metal screws or parts required.
I initially tried printing them as one piece, but that worked our spectacularly poorly..
no sponge or filament cleaner . I have another plan for that from the roll side
