Single Piston Auto Tapper

thingiverse

I'm playing tap my Katamari, a very simple tapping game that grew tiresome after a while. So, I built a machine to take over the tapping duties! To get it up and running, I added a small motor, 9-volt battery, and a switch - voila, a tapping machine was born! I utilized the single-piston design created by sirmakesalot and tweaked it for my stylus's radius. A small hole in the Gear Housing Axle allowed the motor spindle to fit perfectly. Then I placed the stand above my phone, holding everything securely in place. Pistons are indeed the best way to convert rotational movement into vertical movement! Post-printing was a breeze. Assembly required some finesse: I used a small torch lighter to help me join the base to the stand, which had extremely tight tolerances that needed a bit of shaving and melting to get just right. Once assembled, you'll need to test out the distance between your phone and the piston - mark it down and screw or bolt it into place for perfect alignment. The switch, motor, and 9-volt battery I used were all second-hand, along with a wire attachment thingy that made everything work seamlessly together. I designed this project using Tinkercad.
