Filament rewinding system

This video shows the interaction between my filament rewinder and the filament feeder.
The filament feeder is actually a filament spool holder with a special feature: it has an adjustable brake.
Why the brake? Especially during fast spooling processes with a cordless screwdriver, the filament must always be braked manually so that it remains under tension. This is particularly important for sudden stops so that the filament does not unwind in an uncontrolled manner.
The braking force is adjustable so that both cardboard and plastic rolls are braked adequately and evenly.
The filament feeder and filament rewinder can be simply plugged together.
Both models are available at www.Printables... under the following links with all print files and detailed descriptions.
