Here is what the test print look like for my version with small blades.
Not super conviced It seems like there will be too much drag.
Good Idea but I would reduce the diameter of the hub at least to motor diameter to avoid drag: 63mm
Could you explain what do you want to achieve with your design ? Is it necessary to use such small blades ?
Tks
Wanted to reuse existing blade designs.
It it is not possible to make it smaller because the Bolts have some interferences then.
Hub diameter is 80mm
The flite prop is uploaded and linked somewhere here on the forum, that’s an alright prop

Works well for the 63100, might have too much pitch for the shorter outrunners.

I tried it. I didn’t really like the appearance of the part. I didn’t notice any particular increase in strength. I heard that thermal post-processing is needed.

Realy nice. Unfortunately I don’t have a lathe.
I did an adapter like this with a 3d printed part and a bolt. Works well (but need to be balanced like any prop)

Which blades are you using at this propeller?
Can you re-share this file?
I am not the owner from the file.
FWIW I have printed @Bzhwindtalker 's prop shared here: Shared projects - Industries, Unique & fun DIY electronics and kits Thanks Adam!
I have printed the hub using PETG-CF on my Bambulabs P1S and the props using an old AnyCubic Photo UV resin printer… using the Siraya Tech Blu resins - I have used the Black Lava - with amazing results. I have used this for 10 sessions and no signs of degrading.

Just an update (i mentioned on my new waist build)… these blades would eventually break after several sessions but discovered this is due to me accelerating too hard. Now i ramp up slower and havent broken a prop since.
