Planetary Gear Visualizer (Multi-color with no MMU)

prusaprinters

<p>I made this version for people who don't have an MMU but want to do multi-color without having to paint it.</p><p>I used emmett's OpenSCAD file to create the planetary gears &gt;&gt; <a href="https://www.thingiverse.com/thing:53451">https://www.thingiverse.com/thing:53451</a></p><p>It uses 3 8mm(D)x3mm(H) magnets. &nbsp;The center magnet needs to be glued in place. &nbsp;The outer magnets should be press-in, but can be glued if needed. &nbsp;The 2 outer magnets are to keep the outer part from spinning. &nbsp;They attract to the screws in the corners of the motor.</p><p>Print Main.stl in black (or the color you want).<br>Print Sun_Cap.stl in yellow (or the color you want).<br>Print 6 of Planet_Cap.stl in whatever colors you want.</p><p>Glue the caps to the main part. &nbsp;They are keyed, so they line up perfectly.</p><p>* Edit<br>Shortened the post where the middle magnet mounts. &nbsp;It was pushing the Sun gear out too far and causing minor friction.<br>&nbsp;</p><p>* Edit 2<br>Since this is a Planetary Gear, I decided to add new caps to look more like planets/sun (3D effect) if you want a more "Planetary" look.<br>They are printed in 2 halves to keep the sphere shape and still not need supports. &nbsp;They will need to be glued together.<br>* If you print these with Prusa Slicer, you will need to go into Advanced settings and turn off "Elephant foot compensation" (set to zero). &nbsp;Otherwise there will be a noticeable gap.<br>&nbsp;</p>
