About this 3D model

This is a 4 in one extruder upgrade that'll: 1. Allow you to print TPU 2. Have adjustable spring tension 3. Have smooth filament input 4. Hook allows for better cable management The roller/bearing is aligned so that the filament perfectly enters the extruder, and it also relieves stress on the filament and stepper motor by reducing the friction and twist angle.
