In reference to you saying you don't really know CAD, they say this is the easiest 3D-design software to use... https://www.rs-online.com/designspark/m ... l-software

I make my props with thick blades then file the leading and trailing edges until sharp. I use a 3-bladed prop design.

Of course, i weld them together from aluminum because they are 8" diameter...

Hey Steve, I'm a new user of this site looking to upgrade my propulsion system. I was wondering if you ever perfected this design, or have an alternative design.

This is my fourth year of participation in the MATE competition, and my team would like to raise the bar this year.

I haven't done anything with this besides the initial testing.... it's hard to beat the true Bluerobotics thrusters but whether they fit into your budget is another thing.

Nice design. Did you sand down your prop before you mounted and tested it? The reason i'm asking, and this might be totally irrelevant, but a few years ago we pulled out our 18' fan when it got hot one week, and noticed it wasn't blowing as strong as it used too. It was spinning fine, but I saw there was a good build up of dust on the blades. I cleaned the blades and the air flow was probably double what it was before I cleaned them. Might be an interesting experiment??

I didn't really do any post clean up after printing just minor sanding but I bet your right that if I did it would be a lot more efficient.
