Prusa Filament Feeder with Ball Joint Head

thingiverse

A two-part filament feeder that keeps a steady filament tension, preventing the filament from unwinding from its spool and twisting around the holders. ##### Key Features * A special flap-spring keeps the filament from rewinding back and tangling; * A ball-joint prevents the filament from bending at sharp angles when printing high layers; * The leg/stand is specifically designed for Prusa i3 printers, ensuring there's just enough distance between the print head and the leg hook if the printer is properly assembled; * Suitable for 1.75 filaments; * Easy to install and remove; * The head can be easily replaced if the spring wears off or breaks. ##### Essential Information To click the head into its stand properly and ensure the flap-spring functions correctly, it's crucial to calibrate the **extrusion multiplier (wall thickness) accurately**! You can use the Wall Thickness Calibration (Part Fitting) Test on Thingiverse to set the correct value, or simply adjust the *Flow* parameter in your Prusa live settings until the two components fit together perfectly.
