Hello 3D print specialists, this is not my department but I find very difficult to buy certain size props, in this case extremely light (2-3 grams) at some 9 to 10 inch diam. with very low pitch like 2.3 to 2.8 as an examples. for micro light scratch build very slow flying models (100 to 150 grams AUW).
Just wondering if it could be made by 3D print for practical/reliable use?

Re-shaped modified props, still too heavy for my like as a sample.
