This self-starting Miniature Roller Coaster took more than 900 hours to design and print.

Gif: YouTube – 3d_coasters – That’s probably less than you’re going to spend waiting in a fun park. Tired of endless hours waiting to travel to your local amusement park on the latest and largest roller river? Why don’t you spend all that time designing and printing your own roller coaster like the 3d coasters in Youtube?

The NoLimits 2 coaster is much worked out – as detailed in a recent video shared on your YouTube channel – far more than you would like. The design of the track and the coaster itself, assembled from 2.983 different parts, took over 600 hours with a software piece called 3D modeling. Fusion 360. When parts are finished, 3D printing can be completed while the remaining modeling takes over 800 hours of 3D printing and seven filament rolls.

When the 3D printer was finished, all parts had to be manually sanded and finished, especially the path pieces so that the friction was smooth enough, which took another 35 hours to minimize unintentional friction. The eight-seat minipass coaster was assembled from there for twenty hours and the course was fixed for 10 hours to ensure that a single circuit had been completed after launch. It was then completed.

Unlike traditional coasters with a large hill and steep descend at the beginning, providing the coaster with all the energy it needs, the coaster imits more modern designs that instantly speed up the ride car and its passengers by using electronic boot systems. An Arduino with a custom code is running all NoLimits 2, including a single DC engine and 5 servo devices. Its creator has not yet found Coaster enthusiasts on a scale of 1:35 to manage its creation, but with its terrible speed, it would seem doubtful if they would survive the extreme G forces.
