Filament Spool Winder (Yarn remix)

this is a remix of some Spool Winder found on the net based on the famous Yarn model; I redesigned some parts and added the rod (guide) to distribute the filament neatly.
The mechanism is very solid and conceptually simple to use: you can transfer 1kg of filament in a few minutes.

IMPORTANT: as shown in the pictures, it is useful to brake the filament with the hand that distributes the filament, while the other hand turns the spool to be loaded.
