Cow's Dual Bowden MK2 (for Prusa i3 Mk2 clones)

Cow's Dual Bowden Extruder MK2 (Ramshead) Couldn't find a dual extruder I liked, so I made my own! This is designed for Prusa i3 clones, especially those who use the Prusa i3 MK2's universal X mount. Fan nozzles in the images are not the latest versions!Will upload BOM first chance I get! Features: Universal 22.5mm Prusa i3 X Mount E3D v6 Bowden Extrusion Inductive Probe Independent Z-adjustment Single or dual extrusion Optional PWM Turbine for part cooling Standard E3D fan cooling Known issues and planned features for MK3: Z-adjustment bends on the base plate. Keep an eye on this while adjusting. Will split the base plate so that each extruder and z-probe can be removed without disassembling the Z adjust. Major adjustments to the Z-adjust accuracy and ease of use coming. Major adjustments of the turbine shroud coming. Assembly tips: I used two springs from ink pens for the Z-adjust to save money Attach the "Fixture" to the "Base", but do not tighten until the Z distance is adjusted. Adjust primary extruder's Z distance only until the nozzle touches the bed, then use the software Z offset in your firmware to align accurately. Don't trust model measurements for tool offsets! Calibrate manually with test prints. Minor flexing in the fixture adds up. Let me know if and how it works for you!
