Stake and joiners, the curved joiner fit the approximate curvature of a ~180cm pool noodle. But the curve is of course adjustable so I think from 150-200cm should be fine.
I print with 3 wall parameters and 10% infill. The “handle” section of the stake needs to be very durable, I suggest making it solid with 6 wall parameters.
If you like my designs please consider donating a coffee or any amount really, I appreciate the gesture.
