I made for my dinghy. Awesome stable! I printed 2 times one turns clockwise another counterclockwise.
Its 360% in size and the hole in the middle has 12mm. 95% infill. 0,4mm layers, no support. Printed on Anet E10
Nice, Did you try them already? How does it perform?
Unfortunately not. I cant wait to test it on Holiday maybe in 2 weeks. I got a 2,4kw brushless motor with 750KV to run with it. Running in 10:45
