When using new full spools, the filament can go of the spool because the extruder is pushing the filament back up.
This adapter ensures a better fit for 50 mm spools on 32mm spool holder. And as an added bonus there is a guard that feeds the filament to the printer. This guard keeps the filament on the spool, so you don't have to worry about it.
Prototype is teseted for more then a month and we never encountered filemant going of the spool.
This product is in Beta because after succesfull testing the prototype we made a few improvements. We made it lighter and stronger, but those changes haven't been tested properly.
During the Beta period we offer this product at a discount price to our Beta testers.
