Marbulous Double Long Ramp

Marbulous, Marble Genius, Marble Run, Toto Toys Standard
Post 35mm h x 27.5mm dia, Boss 6mm h x 23.5mm dia
Posts 100mm between center, 17.5mm I.D. tube, 4deg slope

This model has 3 posts and measures 1 post high.

I set the support overhang angle at 60deg to provide support for only the post undersides.
I set the support for only touching buildplate.

The rib was added to provide more rigidity and to reduce support needed.
