Useless Mechanical Advantage
thingiverse
Turn the crank clockwise and watch as small pulley #1 on axle A swings larger pulley #2 on axle B into action. Larger pulley #2 then puts pedal to metal, spinning pulley #3 on axle B at breakneck speed. Pulley #3 doesn't stop there - it propels small pulley #4 on axle A forward in a frenzy of movement, ultimately leading to an eternity of . . . just kidding about that last part. Cranking away is ridiculously satisfying and will become your new go-to pastime. You'll love the feeling of accomplishment when you watch this beast of a machine whir into life right off the printer bed - minus those pesky supports. Project Details **Instructions for use:** Print in one seamless piece, carefully allowing support structures to guide your 3D model. Next, safely break away any remaining support beams and snap some rubber bands around your masterpiece. Finally, give that crank a good ol' fashioned cranking! This labor of love typically takes approximately 5 hours to complete.
