3Dator Bowden Extruder

This is bowden type extruder. It is designed to be in a small formfactor, support hard Filaments like old PLA, but also print flexible materials like Ninjaflex. It uses 1.75mm filament. With the opener you can release the stress from the filament to change it quickly.
The Parts are designed to be printed without Supports.
It can be mounted on the outside of your printer with the adapter. The adapter mounting holes are compatible with the Airtripper Bowden Extruder.
Also you could mount it in your Case like in the 3Dator. The stepper motor goes inside and the extruder outside. The material between should be 4-5mm.
