I have dual 5015s on my KE and the standard model would not fit. I didn't want to remove the fans as it would skew the results with the variation in weight. It's not great for the placement as I know it should be as close to the nozzle as possible but this is the best I could do with my very limited modeling skills.
Please feel free and fix/remix to make any corrections.
The author remixed this model.
I lengthened the arm that screws into the back of the extruder so that it will fit with larger fan mods.
