Mechanical Dice Roller

For this project, I worked in a group of four to design and make a simple mechanical device. We came up with a product that will roll the two dice, shown in the photos when the handle us turned. The handle is linked to a rack and pinion system that lowers the floor that the dice are sat on down. We removed three teeth from the pinion to allow the floor to pop back up after compressing a spring, when the handle is turned to a certain point. It is this popping action that flips the dice into the air. The acrylic housing on the top of the device prevents the dice from flying off and getting lost. The body of the device was made from hardboard as it could be easily and quickly cut on a guillotine. It provided a sturdy frame to mount the moving parts when glued together.
