Super Clicky Fidget Button

prusaprinters

<p>This is a 2-state click button with an internal mechanism similar to that of a retractable pen.&nbsp;</p><p>This can be used with or without a long M3 bolt to transfer the click action into a secondary linear or rotary motion. Use the case with holes to see the cam pop in and out of view each click.<br>&nbsp;</p><figure class="media"><oembed url="https://youtu.be/bJq6pNM4eR8"></oembed></figure><p><a href="https://youtu.be/bJq6pNM4eR8">https://youtu.be/bJq6pNM4eR8</a></p><p>&nbsp;</p><h3>Hardware</h3><h4>Required</h4><p>A spring that is <i>about</i> 15mm long and 5mm in diameter. The design can use larger and smaller springs, but this size worked best for me.</p><p>Spring harvested from a standard click pen are a little longer than needed, but should work. If the click mechanism feels too stiff, shorten the spring with wire cutters.</p><p>I had a little success creating a spring out of PLA filament softened in hot water. This would probably work if you're willing to test different coil sizes, but metal springs will still be best.</p><h4>Optional</h4><p>A long M3 bolt to transfer the click action out of the device for some secondary purpose - or just to demonstrate the change in distance caused by the click.</p><p>&nbsp;</p><h3>Printing</h3><p>All parts can be printed without supports.</p><p>The cam includes a thin 1 layer bridge over the bolt hole. If you intend to use a bolt, puncture that bridge with the bolt.</p><p>&nbsp;</p><h3>Getting a good click</h3><p>I found the the button click improves after using it for a while.</p><p>Some people have added wax or Vaseline to the sliding parts.</p><p>If the button is still sticking, try printing the cap and button at a 0.16mm layer height, and the cam at 0.2mm. This guarantees that the sliding surfaces have slightly offset "steps" and are less likely to catch.</p><p>&nbsp;</p><h3><strong>Can I sell copies of this?</strong></h3><p>Yes!
