ebay e3d v6 clone bowden nozzle, with a direct drive for a makergear m2

thingiverse

the nozzle screws into the extruder mount from the bottom. The top of the nozzle is a 1/8" npt female pipe thread. This threads onto the plastic nub of the extruder and helps keep things aligned. The model is parametric and can be modified in inventor should you need to change the nub diameter or design. The split opening acts as a spring and further supports the nozzle. I had to use a vice to hold the plastic and thread in the heatsink extruder. It has 40mm fan mounts integrated but I did not use them in the end. They do provide extra strength. The two versions have the fan ears in different locations. I would recommend the version 3. I have been using 3dx tech abs/nylon alloy with good success for very high temp parts. I like it more than ABS and the cost is the same. This design is very stiff but allows for poor print quality. I had good results with slic3r and printing 5mm tower supports. Use a strap wrench to hold the metal extruder while attaching to the plastic. v4 updates: Improved geometry to allow easier re-loading of the fillament. Re designed the nub the nozzle screws to for easier threading. Thickened up the extruder bearing area for better fillament pressure support. I recommend this over my prior versions. V5 has the wings removed and is compatible with my latest 50mm fan mount.
