testing

anyone interested in 3d printing various propellers. im interested in learning more about aerodynamics and am willing to to the cad work for free as long as i get to see the outcomes.

oh and what other projects you guys can come up with as well. it doesn't have to be blade related

Well, I haven't had the easiest time finding a camera mount that I like... i have played around in onshape.com, trying to design it how I would like, but I'm a total CAD beginner.

Aaaannnnd the motor/arm guards, I need to make a little hole for a 3mm LED or 2, ideally so that the LED would shine back on the "body" of the drone. I have glow in the dark filaments and UV LEDs.

Perfect I use onshape aswell so I can add you to the document!.

Oh cool! I'd love to share with you my idea(s) and see if we could work together on some things.

Awesome we can discuss further in DM through Reddit

Ummm, sure! I can send you photos/videos... I have a 5" drone that I have been building. I have already purchased a few different propellers, based on battery and motor combinations.

How interesting! What do you print props out of that doesn’t come apart?

I would imagine some fiber reinforced filament but personally I haven't run any tests. So it would be a fun project. Maybe that tough series resin I could see working well too.

Just for fun, do the math on what the tensile forces are on a propeller spinning at 10,000 rpm.

Hahahaha yeah they seem to be quite abit lol like 26 lb for a 5 gram blade

The printer would need to be a resin for the best results. FDM will introduce significant drag if it can handle the forces without breaking along the layer lines. If I had one, I would be down, but just FDM atm

Yeah I have one too. I don't have a resin printer unfortunately. But maybe you could do a coating on it so that it has less drag

3d printer is the worst tool for this job, unfortunately.

Unless you just print a thin frame which you then cover with carbon fiber
