<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/draft/360322/2023-12-15_92eaaa9691a14.gif"></figure>The gearbox used in this design is modular and will be released as it's own series soon™, if you have any thoughts or feedback please share so I can continue to improve the design!<h3>Modifications and Add-on Designs</h3><ul><li>[NEW!] Remix Templates<ul><li><a target="_blank" href="https://makerworld.com/en/models/123219" rel="nofollow noopener">Threaded cap</a></li><li><a target="_blank" href="https://makerworld.com/en/models/125073" rel="nofollow noopener">Hexagon gear driver</a></li></ul></li><li>Gearbox modifications<ul><li><a target="_blank" href="https://makerworld.com/en/models/99992#profileId-106623" rel="nofollow noopener">High torque conversion kit (1:2 ratio)</a></li><li><a target="_blank" href="https://makerworld.com/en/models/105586" rel="nofollow noopener">1:3 ratio gearset</a></li><li><a target="_blank" href="https://makerworld.com/en/models/108803" rel="nofollow noopener">1:4 ratio gearset</a></li><li><a target="_blank" href="https://makerworld.com/en/models/105590" rel="nofollow noopener">1:5.5 ratio gearset</a></li><li><a target="_blank" href="https://makerworld.com/en/models/110188" rel="nofollow noopener">1:7 ratio gearset</a></li></ul></li><li>Toroidal ring designs<ul><li><a target="_blank" href="https://makerworld.com/en/models/102279" rel="nofollow noopener">Toroidal Launcher Mini Rings - 100mm pitch</a></li><li><a target="_blank" href="https://makerworld.com/en/models/97633" rel="nofollow noopener">Toroidal Launcher Mini Rings - 150mm pitch</a></li><li><a target="_blank" href="https://makerworld.com/en/models/102728" rel="nofollow noopener">Toroidal Launcher Mini Rings - 200mm pitch</a></li></ul></li></ul><h3>Specifications</h3><ul><li>Three stage planetary gearbox with 1:48 gear ratio (overdrive)<ul><li>0.75mm gear module for ultra-smooth performance (24/72 teeth)</li><li>10mm hex driver for connecting gear stages</li></ul></li><li>Toroidal ring design with four blades (1.2mm thick) available in three sizes<ul><li>100mm diameter, 150mm pitch</li><li>125mm diameter, 175mm pitch</li><li>150mm diameter, 200mm pitch</li></ul></li></ul><h3>Printing tips</h3><ul><li>All prints pictured were printed using Bambu Basic and Matte PLA</li><li>For best results run flow rate calibration and thoroughly clean build plate</li><li>The launcher gears are available in two print profiles with the following changes to the standard 0.20mm profile:<ul><li>Arachne wall generator</li><li>5x top and bottom walls, 25% infill</li><li>75 m/s inner and outer wall print speed</li></ul></li><li>The toroidal rings are available as a single print profile with the following changes to the standard 0.20mm profile:<ul><li>0.6mm line thickness, Arachne wall generator</li><li>75 m/s inner and outer wall print speed</li></ul></li><li>The launcher housing prints with the standard 0.20mm profile.</li></ul><h3>Launcher Parts</h3><ul><li>Launcher Gears<ul><li>SunGear24.step [3x]</li><li>PlanetGear24.step [9x]</li><li>PlanetCarrier24.step [3x]</li><li>RingGearDouble.step [1x]</li><li>RingGearLid.step [1x]</li><li>RingDriver.step [1x]</li><li>GearDriver.step [1x]</li></ul></li><li>Launcher Housing<ul><li>HousingBase.step [1x]</li><li>HousingRingLid.step [1x]</li><li>HousingCarrierHolder.step [1x]</li><li>HousingCarrierThreads.step [1x]</li></ul></li><li>Toroidal Rings<ul><li>ToroidalRing100.step [1x]</li><li>ToroidalRing125.step [1x]</li><li>ToroidalRing150.step [1x]</li><li>ToroidalRingDriver.step [1x]</li><li>ToroidalRingLauncher.step [1x]</li></ul></li></ul><h3>Launcher Assembly (Gears + Housing)</h3><ul><li>Assembly the planet carrier with three planet gears and one sun gear as shown below. Repeat for all three planet carrier assemblies.</li></ul><figure class="image"><img src="https://makerworld.bblmw.com/makerworld/draft/360322/2023-12-31_efae722ebe2db.gif"></figure><ul><li>Use the shorter hex drive to connect two sets of gears. 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't remove the gear assembly and repeat this step.</li></ul><figure class="image"><img src="https://makerworld.bblmw.com/makerworld/draft/360322/2023-12-31_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/draft/360322/2023-12-31_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/draft/360322/2023-12-31_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><h3>Toroidal Ring Assembly</h3><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><h3>Changes</h3><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>
