Bowden Bracket for Greg/Wade Extruder Remix

thingiverse

This remix of the excellent Stu_Dku bowden bracket allows you to attach your classic Greg/Wade geared extruder on the back beam of your Sapphire-S CoreXY printer. It can be adapted for use with more printers, and that's why my source file is included as well. Use it freely for commercial purposes; just be sure to share your modifications and acknowledge your sources so others can benefit too. The Greg/Wade Extruder in the picture is the classic hinged greg wade extruder designed by Greg Frost (thing:8252), which I've paired with Richard Horne's (RichRap) excellent Greg style guidler modified with grab lever (part from thing:60531). Working together with this bracket remix, these three components make a powerful combination that allows me to run my upgraded Sapphire-S (equipped with high torque motors) at high speeds. I've tested it successfully at 120mm/s. Changes have been made to the original design: The input nozzle has been reduced in size to fit the classic Greg/Wade extruder and relocated to the middle of the distance between the two holes on the bracket. These modifications enable you to mount the extruder inside the bracket, as opposed to positioning it outside. Although mounting it on the other side still works fine - I've used the original Stu_Dku bowden bracket since 2014 without any issues - you cannot install the extruder inside the bracket if the nozzle is not positioned in the middle between the holes. Therefore, there you have it. Enjoy!
