hollow universal joint - printable & parametric

prusaprinters

<p>Hollow universal joint, printable as a single unit &amp; parametric with openscad.</p> <p>The scad's got a decent amount of comments, I might clean it up and upload a better version later, but it's pretty straightforward.</p> <h3> Instructions</h3> <p>Print! The joint+ring stl should print well - there's a 1mm gap between the ring and the joint. Be sure to use Brim or some other method to get the part to adhere strongly.</p> <p>Doesn't require any connectors, the pieces just snap together.</p> <p>Idea came from <a href="https://www.thingiverse.com/thing:25872">http://www.thingiverse.com/thing:25872</a>, also used <a href="https://www.thingiverse.com/thing:3140">http://www.thingiverse.com/thing:3140</a> to start the openscad bit, but I went through and parameterized everything.</p> <p>To resize, all you should need to change are the outer_rad and wall parameters - the first is the overall radius (so the part will be twice as wide), the 2nd is the wall thickness.</p> <p>As written, the inner diameter is outer_rad<em>2-(wall</em>2+1).<br/> The part displayed is 20mm outer_rad and 3mm wall, so outside is 40mm around and inside hollow is 33mm.</p> Category: 3D Printing
