<h2>Toroidal Launcher</h2>This is an original design created for the <a target="_blank" href="https://makerworld.com/en/contests/5" rel="nofollow noopener">Flying Objects design contest</a> and features a handheld three-stage planetary gearbox that launches a toroidal ring over 3000 RPM! The design is 100% 3D printed; all pieces press fit together and no additional hardware is required.<figure class="image"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000093385/design/2023-12-15_92eaaa9691a14.gif"></figure><boostme><boosttitle>Boost Me</boosttitle><boostcontent>If you&#39;re interested in seeing more designs like this please consider boosting to support development of future projects.

Align both planet carriers and hold them with one hand while holding the double ring gear in the other hand and slowly turning as you close the gear; once closed insert the assembly into the main housing to hold secure. The gears should spin freely; if they don&#39;t remove the gear assembly and repeat this step.</li></ul><figure class="image"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000093385/design/2023-12-31_f1371c6d57ee6.gif"></figure><ul><li>Use the longer hex drive to connect the last set of gears and then assemble with the threaded cap as shown below.</li></ul><figure class="image"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000093385/design/2023-12-31_4926c45fbbf51.gif"></figure><ul><li>Carefully mesh the single ring gear with the planet gears taking note of the 2mm flat section that is positioned towards the main gear assembly as shown below. Use the same method of rotating while slowly closing and covering with the cap to hold secure.</li></ul><figure class="image"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000093385/design/2023-12-31_54c6fffceb4e5.gif"></figure><ul><li>Done! The assembly should spin smoothly with the output shaft making 48 rotations for every one turn of the input knob. Performance depends on printer tolerances and filament used; for best results use the include print profiles with Bambu Studio (supports many different printers). A bit of lubricant can also be added to the gears to improve performance.</li></ul><h2>Toroidal Ring Assembly</h2><ul><li>Insert the hex drive into the interlocking driver; the clearance is tight but it should be a snug fit.</li><li>Insert the assembled driver into the output sun gear, the fit should be the same.</li><li>If the driver does not stay secured when launching the ring a small amount of CA glue can be use.</li></ul><h2>Changes</h2><ul><li>v1<ul><li>Initial release; files now available in v1old folder</li></ul></li><li>v1.1<ul><li>Updated print profiles with improved settings for gears and rings</li><li>Improved single color print profile, fits on A1 mini and objects are laid out to allow skipping</li><li>Improved clearance of gears and overall meshing</li><li>Updated toroidal ring to use the same launcher as the mini rings<ul><li>Print profile includes 3 sizes (100mm, 125mm, 150mm)</li></ul></li><li>Updated assembly instructions to have fewer steps with a GIF for each one</li></ul></li><li>v1.1.01<ul><li>Added new section for template designs intended for remixing</li></ul></li></ul>
