Bought Tevo Michelangelo and had two 4010 fans as blowers but the adapters onto them are not great. I set out to adapt the great circular design to a dual fan system. I'm ridiculously beginner level and a lot of this is not the cleanest design, but the results are pretty great. You should be able to print without any supports needed, possibly on the screw holds but that is about it. Stock screws can be used. I've found sometimes I need to clean up a little bit before it fits into the fan duct. Tested with pla, petg, and hips.
