About this model

I broke a blade on my desk fan I built out of an old PC fan. So I decided it would be a good chance to learn how to design a fan... My final design is basically two fans in one that directs all of the air flow straight forward with no turbulent side splatter off the edges of the blades. The original fan blade assembly was injection molded with the shaft in place. You have to cut the old assembly apart with nippers to free up the shaft and magnetic ring. To fit the parts to the new fan assembly, I made a jig. It presses the magnet ring to the proper depth and holds the shaft perpendicular to the fan's plane for gluing. I used gel super glue and just put a dollop of it into the hole before inserting the shaft and pressing the jig in to hold everything while the glue sets up. I found the best…
