This is a remix of the dust shoe by yohabi. I really liked the design and the idea of using the spindle as a vacuum motor at the same time. I re-designed this thing to allow for easier access to the collet and the spindle for replacing the bits. None of the parts will fit with any of the original parts from yohabi because they were all adjusted or remodeled in some way.
All parts were also set up in such a way that you shouldn't have to use supports for any to print correctly.
The fan blade should be pressed into the top of the collet and placed on after the main body is attached. You will notice holes in the base to make it easier to bolt onto the bottom of the spindle motor. You could always cover those holes with tape but I don't think they affect the suction at all. The nozzle then press fits in under that part. I cut bristles off of a paint brush and super glued them into a slot in the nozzle. I then cut a water bottle in half and hot glued a filter from a small datavac vacuum I have to finish the setup.
