Gravitrax double tunnel
thingiverse
I used the base of the Gravitrax roller coaster designed by MK_Design and modified the inlets to accommodate marbles. The ring component originates from MK_Design as well. My design closely resembles the tunnel structures found in the original components. The double tunnel system's foundation is rooted in the Gravitrax roller coaster, which was expertly crafted by MK_Design. I've made adjustments to the inlet areas to ensure a smooth flow for the marbles. The ring part also comes from MK_Design. My creation draws inspiration from the tunnel designs that are characteristic of the original components.
