<p><strong>Update 16.04.2020: </strong><a href="https://www.youtube.com/watch?v=wbBhOSn0l5E"><strong>found on Youtube a track with the curves</strong></a></p><p>I've seen some curve tracks for Gravitrax, printed and tested them.</p><p>Then there were some thoughts in my mind, which curves, with which radius and angle,</p><p>will be possible and useful, and can I increase the grade (angle of slope) .</p><p>After a while I find a schematic which curves are possible, but not a lot of them are useful.</p><p>Nontheless, I designed, in my available CAD, a custumized curve, to switch</p><p>between curve size, angle and grade.</p><p>The four curves I loaded up, are the useful ones for me.</p><p>(There is a picture that shows the possible curves to choose)</p><p>The end of the curves are designed a little bit stiff, so they fit a little bit strong into the plates.</p><p>But so the Curve 1x120, 1x240 and 6x60 can be used without support.</p><p>The Curve 2x180 need some support, like shown in the picture, or it will tip over.</p><p>They all have a "angle of slope" about 35 degree, so the marble can went troug with&nbsp;</p><p>some <strong>high speed</strong>. <a href="https://www.dailymotion.com/video/x79s5nv">(see Video)</a></p><p>See also my <a href="https://www.printables.com/de/model/246405-gravitrax-s-curve">S-Curves</a> here.</p><p>Update 04.05.2019: I added 2 more: 2x60 and 2x120</p><p>Update 18.08.2019: all the curves are now available with 2 "angle of Slopes" , 0 and 35 degrees</p><figure class="image image_resized" style="width:69.12%;"><img src="https://media.printables.com/media/prints/246407/rich_content/ce64f2c6-a4fa-4f2b-b117-917aee6748e7/curve.webp#%7B%22uuid%22%3A%22a7bf7d12-3662-48eb-a46f-848596aa90c9%22%2C%22w%22%3A800%2C%22h%22%3A347%7D"></figure><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Creality</p><p><strong>Printer:&nbsp;</strong></p><p>CR-10S</p><p><strong>Rafts:</strong></p><p>Yes</p><p><strong>Supports:&nbsp;</strong></p><p>Yes</p><p><strong>Resolution:</strong></p><p>0,1</p><p><strong>Infill:&nbsp;</strong></p><p>20</p><p><strong>Filament:</strong> enotepad PLA wood</p><p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p><p>Category: Toys &amp; Games</p>
