bernis simple bowden extruder

With the circulating on the net extruders I'm not particularly happy. I have some built or printed me about it. Either they were too poorly constructed, poorly print or did not work the way I wanted to. But mostly also all came together. So sit down, worked really long and tried to realize the best of everything without a disadvantage to take with. And you know: Simple is always the hardest. After about 5 variants has a proven super and also proved perfect in practice after many optimizations. The assembly is straightforward and there are only 2 printed parts. Other than a few screws and washers no additional mounting material is required for the extruder. You will receive all the necessary parts, except the motor Nema 17. (Which you have probably already is.)
