Cradle for Laser Experiment by theroar Mar 6, 2013


I have a Lasers module for my students and we are experimenting with parts from an old laser printer. The part was sweet, but I needed it at an exact height for our laser. Enter the Cradle for Laser Experiment.

Printed at 5 percent. Came off the base, so I just printed the top the second time and attached it some ABS slurry. The result was awesome. When the beam strikes the device, and you spin it, you get a straight line of laser light along a wall. Not sure what it would cost to buy such an experiment, but Free/salvaged always makes me smile. =) I have included the entire print, and the two versions that I ended up gluing with abs slurry. You can see the beam on the back wall a bit. The effect is much cooler when you have the device spinning faster. Another neat note, I thought the device was on a bearing, but it is really a electromagnet so it is floating.
