<p><strong>Instructions:</strong></p><ol><li>Print the nuts</li><li>Print the TestBolt (if you want to check the fit)</li><li>Print the main bolt, but pause printing about halfway through to add the nuts.<br><br>NOTE: Every time I've resumed the paused print, I've missed a long strand of ooze that seems to appear as soon as I press Resume - so be prepared to wipe it off while the print head returns to the bolt, otherwise you'll have some annoying clean-up.</li></ol><p>My print (nut_space=0.8) left the nuts catching on the bolt a lot, but after working them for a while (especially over problem spots) it's much smoother now.</p><p>I also tried adding some silicone lubricant to the shaft early on, but I'm not sure if it actually helped long-term.</p><p><strong>But what is it?</strong></p><p>A fidget toy where the clockwise and counter-clockwise nuts are stuck on a bolt that lets them spin in both directions.</p><p>This is the same idea as the original <i>Two Way Threaded Screw Fidgeting Toy</i>, except:</p><ol><li>It's customizable in OpenScad, with no external libraries</li><li>When I tried slicing the original, Cura kept leaving empty spots where the shaft met the ends, and both of my attempts to print broke there. &nbsp;This bolt is one solid piece.</li></ol><p>The default settings should mostly work, but if I print this again:</p><ol><li>I need to remember to shave down the inside-bottom of the nuts (to move smoothly despite some expansion on the first layer)</li><li>It might also be worth increasing nut_space above 0.8 (1.2?) to make the nuts move smoothly.</li></ol><p>&nbsp;</p>
