Robo 3D R1 Dual 50mm fan mount

cults3d

A dual cooling fan mount for the Robo 3D R1 that moves the fans back out of the way when using a larger hotend. I built this to work with my E3D v5, but it may work with other hot ends. This mount is an improved version of my previous dual fan mount (https://www.thingiverse.com/thing:1444755) that changes the angle of the fans for better clearance and also adds ducts to direct the airflow more effectively. Adding the ducts has really improved my print quality on bridges and overhangs. NOTE:There is a small loss in Z axis travel where the rear fan hits the printer case, I'm hoping to eliminate this in a future version of the mount. The fan mount screws into the right side of the carriage using the two existing holes there. You can either use 3mm screws (that's the way I had my previous mount installed) or if you manage to strip the holes out like I did, you can tap for a #6-32 machine screw which seems to be working perfectly for me. The 50mm fans and fan ducts mount with 3mm machine screws but you may need to drill the holes out slightly or run a tap through to get the screws started.
