tried rotating the model 180° in the slicer and thankfully, that solved the problem. This beautiful little machine took a solid week of 3D printing, which includes 32 hours wasted on a huge piece that failed twice. The reels have been modernized and the display is made of four individual LED matrices that appear as a single unit thanks to some smoky adhesive film. Inside is an Arduino Uno and a giant printed screw feeder that’s driven by a small stepper motor and a pair of printed gears. As they say, the house always wins.ĭrop a coin in the slot and it passes through a pair of wires that act as a simple switch to start the reels spinning. And the best part is, if you put such a piggy bank slot machine out in the open where your friends and neighbors can play with it, you’ll probably make even more money. Wouldn’t you be more likely to drop your coins into a piggy bank if there was a chance for an immediate payout that might exceed the amount you put in? We know we would. Saving money is inherently no fun until the time comes that you get to spend it on something awesome.
