Pestle Rotational Bowden
This extruder mounts on the X-gantry and is capable of rotating. This new mounting location cuts approximately 50% of your bowden length off, and also rotates to further take bend radius out of the PTFE pathing, the end result is a bowden length of -50-60% compared to traditional mounting solutions. Currently working on various brackets to adapt this system to many more printers from Enders to Prusa's devices.
EX: Ender 3 Bowden length will be under 200mm total distance.
