Great simple model for 3D print usability showoff at school.
This is my first land yacht & I had a great time building it. :D
Antoinefro many thanks for publishing it!

Still waiting for wind to be at the same time I have free time, to make first run :(

Ps: The black one in background is from plywood and carbon tubes.
It's designed after antoinefro version but planed to be simple enough
to be hand made by my primary school students.
Steering is made over WiFi using smart phone.
If antoinefro agrees I can publish the files after testing and removing possible errors.
