E3D Dual Fan Mount (Printrbot Plus V2)

I had issues with the stock Ubis hot end from Printrbot so I ordered two E3D extruders and now I'm in the process of printing parts to fit a dual bowden carriage to a Printrbot Plus v2.
This is the model I made for dual fin and nozzle fan ducts. They are designed to fit 40mm cpu fans. Since I didn't have the fans before I printed these, they came out a little warped but I still managed to twist them into a functional position. It uses M3 screws for the fans and one #6-32 to mount the ducts
