I taught high-school physics many years ago. Students really enjoyed demonstrations and labs. Although the equipment often was fairly simple, it also could be expensive, and that cost limited our demonstrations and labs. I think 3D printing offers some great possibilities for teaching and learning physics, especially on a tight budget.
I found several items on the Thingiverse that would be great for teaching physics. If you know of other such things, please post them in this discussion. Or, if you have ideas for other things, let us know about your ideas. Maybe someone will be inspired to create and share these things for those of us who love physics and want to help others learn.

Here's a question our AP Physics students might get this year that arose while playing with one of my printed objects:http://www.flosscience.com/2015/03/conservation-of-energy-conundrum.html
Here's a project I did in physics a couple years ago that might be of interesthttp://www.flosscience.com/2013/05/fun-with-3d-printer-physics-wind.html
I'm glad you included lesson/project descriptions and ideas. Sometimes, we expect people will just understand how and why an object will be educational.
Here's a collection of objects that I've used while teaching physics or ones that I've contemplated using.
Nice collection. Thanks.
I found a few more items on the Thingiverse that would be good for teaching physics. If you know of other such things, please post them in this discussion.
