I’m not very experienced in CAD design and fabrication so I created a very simple model of a bell crank ([Bellcrank - Wikipedia](https://en.wikipedia.org/wiki/Bellcrank)) driven by a servo programmed in MicroBlocks. Here are the parts, which I cut on a laser cutter.

This is a great model of a bell crank, used for ringing a bell even! Can you post a photo of it assembled together?
