My take on a simpler extruder without gears or hobbed bolt.
The PLA (3mm) is feed past the motorshaft and draged/pulled trough.
Its intended for use with all kinds of hot-ends nad carriers.
Im working on my own Hob-end, but since its not a extruded product, or a digital design, its not on thingiverse.
