Helical Sisyphus

I built an interactive marbletrack. Just put a standard glass marble (mine measure 16.5 mm in diameter) and it will roll to the bottom. I must fight my urge to keep putting them on it... https://www.youtube.com/watch?v=BSx1ZfvO8sc I wanted to stress test my printer, and a spiral was the first idea that came to mind. After printing a flat spiral, I thought of using the "track" for something new. Thing #58406 was the original model for the second code version. Printer Settings: Printers Used: Spiderbot Settings Applied: Rafts Used: No Supports Used: No Resolution Selected: 0.25 mm recommended Infill Level Set: 100% Additional Notes: The track's walls are only 1mm thick. To achieve smooth prints, adjust your printer settings for flow, width, and number of primers so you get exactly two or three extrusion lines (excluding bottom struts). This tweak will significantly speed up the print. Since most of the printed area is an outer shell, increasing the print speed greatly shortens overall printing time. Instructions: The current code has some limitations. Ideally, I want it to be fully customizable again. Until then, you can download a set of pre-made STL files with different size options based on maximum width settings. This should provide you with some basic track designs to experiment with... and maybe more will follow soon? Notably, the generated STL model is "clean" but unexpectedly stresses some slicers quite hard. Be aware that due to varying layer thicknesses, noticeable steps (and minor blobs) are present along the spiral slope of this print job. There's a suggested tweak that can minimize this effect somewhat; however, some sanding or scraping may be necessary along certain areas of the track.
