Airless Tire

prusaprinters

<p>These wheels use an airless tire design. The central 3d-printed core is surrounded by a helical coil of cable. I have successfully used these on a mars rover inspired robot, and they deal reasonably well with rocks, sticks, and loose dirt.&nbsp;</p><p>The center has a 16mm square of 3mm holes, for use with a motor hub.&nbsp;</p><p>The model source is a python script, which uses <a href="https://github.com/SolidCode/SolidPython/">SolidPython </a>to generate OpenSCAD code for the 3d model.</p><p>More information can be found at <a href="https://github.com/gwfellows/rover">https://github.com/gwfellows/rover</a></p><p>Make sure to print with 4 or 5 solid layers and perimeters, as well as &gt;30% infill, to ensure the wheels are strong enough.</p>
