A Dual E3D v6 Mount Specifically Edited to Match Heights with the other mount in my library, Uses 1x M4 Screw and 1x M4 Nut to secure the two parts together, and is designed to mount to an existing or newly made NEMA-17 mount with the same holes as a stepper motor. Designed to allow use of a second Bowden groove mount connector for either side on top of the existing heatsink for direct to bowden conversion.
