I designed a second propeller for my boat.
It is a 2 seater kayak. I operate the propeller with my Metabo 18V cordless screwdriver. Has huge performance at 2000 rpm.
you need: 1x 1m threaded rod M10, 3x M10 nut
I have printed the propeller from PLA, of course, PETG is capable.
I Also made a 0.4 Layer - not the best but faster to print..
0.2 Layer is perfect!
