## Extruder. ### Bondtech BMG style. ---------------------------------------- [Bobblejot Website](http://bobblejot.com) [Bobblejot GitHub](https://github.com/Bobblejot/) [Bobblejot Twitter](https://twitter.com/bobblejot) [Bobblejot Patreon](https://www.patreon.com/join/bobblejot?) ---------------------------------------- I decided to finish building my IDEX machine at the beginning of the new year and chose a direct drive Bondtech BMG and E3D V6 combo. My only issue was the Bondtech housing, which I wanted to modify or mirror if needed. This led me to design a simpler version of the housing from scratch, allowing me to make any changes necessary. I removed all injection moulding features and cutouts to keep it simple and easy to print. The body is slightly smaller than the original, with a tighter filament path. The inserted PTFE tube goes further into both sides of the body. There are versions for various fittings, available in left and right-handed options: * M12 press fit fittings * M8 BMG press fit fittings * M6x1 threaded fittings * M10x1 threaded fittings * 1/4" BSP threaded fittings * 1/8" BSP threaded fittings For threaded versions, print at a lower layer height (e.g., 160 micron or less). Designed for 1.75mm filament, same as the original. Extruder ESteps need to be changed to 415.0.
