Making a fan with a cowl. original blades were too big, so i redesigned smaller ones to fit. Still learning fusion360 so yes I know its very crude but it actually works pretty good! Printed the blades and hub in PETG. Black marks on the blades are from my metal file. This is still a work in progress, will upload the cowl once I know it fits. I can also upload whatever file you need to edit the dimensions for the input shaft.
