In an earlier post I’d made a laser cut display case and filled it with some spare gears that I had lying around. It looked good but it didn’t sit well me that the gears didn’t actually work so I set to work designing a moving version.

I present here the result of my efforts. All the parts are cut out on my HPC Laser Cutter and then assembled. Turn the knurled wheel and the set of interlocking gears rotate.

With the display case complete, the knurled wheel is still easily accessible.

Here’s the final result. I’ll put up a proper post with instructions, animation and template files shortly.
