Summary135D x 30P, 150D X 50P, 190D X 75P
A few of my propeller designs for my small quadcopters. I used them on 280-350 size quads. Printed in ABS and Polycarbonate. Support was used. I never tried no support, they were made on a Dimension and Stratasys machine. I have about one hundred more variations of these.
Update: added some more sizes
