That should be it. I have submitted all the files. Please let me know if there are any issues. Thank You.

We know the hub fillets are for machineability but would be a LOT easier to modify the props if you could provide the 3D model without the fillets.

The trailing edge should be the original thickness. Let me explain the rational - marine propellers as use by powerboat - owners send their bronze props to be cupped by the prop shop specialist. They will use an anvil ( or pipe ) and hammer to form the cupping at the trailing edge - just like swimming if your cup your hands you can pull better. So the width of blade from leading to trailing should be shorter due to the curvature and the thickness of trailing edge should remain the same. The trailing edge towards the hubs need to be thicker for strength or the blades will break off. Hub fillets is for machineability.
I have a miniature super charger for hobby engine coming - might be your cup of tea. 2 stage single volute ?

It would be nice to have the original prop vane surface without the tapered addition on the trailing edge. Also without the hub fillets. There are a couple of items I'd like to discuss before doing additional changes, e.g. there is no information on how thick the trailing edge should be. Original prop is getting thicker towards the hub, I made my trailing edge the same thickness as the leading edge, .2mm.

This is the same model as the first project. If you accept this file, I will submit all versions of 7016, after original modifications are approved. I don't want to spend too much time creating parts if this is not exactly what you are looking for.

J-shape
3D modeling of a J-shaped massage tool, much like a Theracane only smaller in dimensions. The tool should be modeled as close as possible to the attached images. The straight portion of the J-shape is approximately 10 inches long and 3/8in in diameter. The hook portion of the tool should form an approximately 180 degree arc and terminate in spherical end of 9/16in diameter. The handle, at the top of the J-shape, should be approximately 3/4in in diameter. The attached jpg images are of the actual tool that I would like modeled and should give you a good idea of it's dimensions. The png file should also provide a good reference. Thanks.
Waterproof Air monitor for drones
Hi, We need a waterproof air monitor for our drones, which has enough airflow to detect particulates, gasses and other pollutants. And has no water ingress. The enclosure needs to be made from plasics, ABS of PLA, and there has to be an atenna for a LoRa module an arduino and batteries. The sensors will be placed directly onto the arduino.
