Cradle for Laser Experiment

thingiverse

The Lasers module in my classroom involves using parts from an old laser printer for experiments. To ensure precision, we utilized the Cradle for Laser Experiment. Initially, the part wasn't at the right height for our laser, so I reprinted only the top section and bonded it with ABS slurry. The result was fantastic - when the laser beam hits the device and you spin it, a straight line of light appears on a wall. Although I am unsure about the market price of such an experiment, using free/salvaged materials makes me happy. Included are the entire print and the two versions glued with ABS slurry; a laser beam can be seen on the back wall. The effect is more striking when the device spins at a faster pace. Interestingly, I discovered that the device floats due to an electromagnet instead of a bearing.
