Description
I practiced shaper3d and this is what I came up with. It’s not perfekt but it works good.
You need a threaded rod m8, 2 x 608 ball bearings and 3x lock nut m8.(I made a small mistake and still needed washers as spacers).
Perhaps you need some technical intuition and imagination when assembling…
I have attached the construction file so you can modify it to your need. You had to print the wing 4x.
You need to saw off a short part of the threaded rod and screw the front and rear part onto the thread. The middle part should be secured with the nuts so that it does not rub against the bodies.
The wings are inserted into the center section. I had to sand a little bit but needed no glue.
I printed it in PETG (on an ender 3 that went crazy during the process....)
It has been working for 3 months with no problems and is also funktional in low winds.
Stick it only on the rod and make sure it is exactly vertical in the ground.
