3D model description

A two-part filament feeder that maintains a slight filament tension, preventing the filament from unrolling from a spool and tangling around the holders.

Features
Special flap-spring keeps the filament from winding back and tangling;
Ball-joint prevents the filament from bending at sharp angles when printing high layers;
Leg/stand is designed especially for Prusa i3 printers. If the printer is properly assembled, there should be just enough distance from the print head and the leg hook.
Appropriate for 1.75 filaments;
Easy to mount and remove;
The head can be easily replaced if the spring wears off or breaks.
Important
In order to be able to click the head into its stand, and the flap-spring to function properly, the extrusion multiplier (wall thickness) should be properly calibrated! You can use the Wall Thickness Calibration (Part Fitting) Test to set the correct value, or you can just tune the Flow parameter in your Prusa live settings, until the two perfectly click together.
