About this model

S-Curve compatible with Gravitrax. Easy to print, needs only support where the hooks are (see image), all other overhangs are 45 degrees at most. Maybe you can even turn off support at all if you print slow enough and your printer/filament handles bridging well. Heavily inspired by S-Curve from MK_Design, but re-modelled from scratch using Fusion 360. The curve is designed to allow the marble to go between other distance plates as seen in the photos. The rails have a cross slope of 15 degrees where the curvature is highest, thus allowing quite high speeds. For nice bicolor effect, change filament at 4,8mm height. I used Fillamentum PLA Extrafill Vertigo Gray for the bottom and standard red for the upper parts.
