<h3>Spiral Track, Compatible with Marble Run Gravitrax</h3> Here are some spiral tracks for the marble run from Gravitrax. Three different models are available, each with a varying number of starts and spirals that complete one full turn of 360 degrees. A double spiral track is showcased in the video, where two marbles navigate through parallel paths. <a href="https://www.dailymotion.com/video/x7pbrf6" target="_blank"> Double Spiral Track </a> <a href="https://www.dailymotion.com/video/x7phyf7" target="_blank"> Triple Spiral Track </a> Each spiral track comes with a corresponding support part. Load the track model and support model into your slicer, then manually position them at the center of your print bed. Both models share the same coordinates. The support model is designed without any gaps, so it must be adjusted in the Z direction by -0.2 to -0.4mm (down) in your slicer. This creates a gap of 0.2 to 0.4mm between the support part and the track model. The support part is printed as a standard model. The design is customizable, allowing for various heights to be achieved. For example, see the list below for alternative height options. If needed, please leave a comment and I will upload the STL files for your convenience. <h3>Update 20.12.2019:</h3> In my slicer program, not all track models were centered with their corresponding support models. To address this issue, I created a circle that encompasses both parts, ensuring they are aligned at their middle points. This ring is placed in the center and duplicated three times to stabilize the poles of the support model.
