This one was quite a technical challenge, but I’m really happy with how it turned out.

The build itself is straightforward — it uses one button, one battery, and one motor to control the lift-and-snap action. I printed and tested the mechanism to make sure i designed it well and it works well when printed, and good news — it really does.

I’ve included everything you need to get started:

Fully engineered and simplified motor action and build

STL files

3MF files (presupported, with print orientation and print suggestion info)

PDF build guide and animations

Parts list with photos

I also did my best to reuse parts from previous projects, so it’s very likely you already have everything needed.
