Meant for 2-walled balloon. Idles well with one (with a flywheel), but will hardly pull any vehicle.</p> </li> <li>You can use metal M5 washer instead of printed one</li> <li>Found that PLA isn't the best material for the design: isn't very slippery, and "fluid" (the clips stop pushing the parts together with time)</li> </ul> <h3>Print instructions</h3><h3>Category: Engineering Print Settings</h3> <p><strong>Printer:</strong> AM8</p> <p><strong>Rafts:</strong> No</p> <p><strong>Supports:</strong> Doesn't Matter</p> <p><strong>Resolution:</strong> 0.2</p> <p><strong>Filament:</strong> Bestfilament PLA Gray</p>
