40mm Blower for Wanhao Di3 v2.1

This is a design based off the work done by BliNDF123. I simply used his concept of a circular, bed-directed air duct, however I completely created this design from scratch using Fusion 360. The original design is not compatible with the Wanhao Di3 v2.1 which is the model I have, hence the remix. This works for 40mm fans. The fan grill was created by cdl1701 and also fits 40mm fans.
