5 blade hub for helice tripale repliable folding propeller

thingiverse

Downloaded the 3 blade hub and thought there weren't enough blades to get good lift. I strongly advise using the reversed blades found here: https://www.thingiverse.com/thing:2626565 since the original ones fold in the wrong direction. Haven't actually flown with it yet, but I've been testing it by spinning it while holding the motor and it produces a significant amount of pull. The hub is identical to the original source design, just with 2 additional slots. It has a 3mm center hole and 2.2mm pin holes for the blades - I found that ground down nails fit in them perfectly and tightly. I can add more blades if needed. (edit: probably should create some sort of propeller cone for it, as it's quite big and flat.)
