Infinity

<p>This is a hollow tube infinity symbol - just for fun. For an added twist (pun intended) I dropped a small (8mm) ball bearing into the print about half-way through (I should have used a slightly smaller bearing as the one I used tends to get stuck).</p> <p>You can see in the photos where I added the ball bearing.</p> <p>The OnShape 3D CAD file for this is located at the link below:</p> <p><a href="https://cad.onshape.com/documents/6e5cf74be55921b7737ad5e5">https://cad.onshape.com/documents/6e5cf74be55921b7737ad5e5</a><br/> /w/dedd6ec1ac1e3045d218dec9/e/5d60206ab5ce9a2085a9c6dc</p> <h3>Print instructions</h3><p>I printed in clear PLA. Lay the print flat on part of one loop - there is very little contact with the build plate due to all of the twists in the loop.</p> <p>I used the "supports on build plate only", plus I added a small custom support where the loops cross over.</p> <p>The inifinity-test.stl file is a short segment of loop you can use for quick printing tests, as well as to get an idea of the inner diameter of the tube.</p> <p>You can use the provided print files, but there is probably plenty of room for improvement in the print settings.</p>
