If you rotate it along the right axis it will show a sinus function.</p> <p>Prusa i3 MK3(S) can handle up to 488 bands in one go. You can easily generate more pieces in one column in .scad file but it takes a lot of time to render and save.</p> <p>When putting on the face shield, place the gap in O-ring at the top of the face shield hook. This way it holds better in place.</p> <h3>Print instructions</h3><p>Use PETG or Nylon. Other materials (PLA, ABS, ...) tend to crack (not bend).</p> <p>Check the density of the spring. The denser, the softer (preferred)</p> <p>O-ring is 3 mm wide.
