E3D Dual Bowden Fed Hotend Mount for Prusa i3

Mounts to Prusa i3 x carriage with 2 M3x30 screws. 3 More M3x30 screws/nuts/washers clamp the set together. The mounting holes are 24mm apart. The nozzles are 26mm apart. Fan duct mounts a single 40mm fan to cool both barrels.

**EDIT:** I made the "clamp" piece thicker because mine cracked when it was fully tight. This could have been an artifact of my 0.6mm nozzle not perfectly forming the grooves. The zip file has the original version.
