Maybe have a look at the Curta for inspiration of a mechanical calculator. There's a 3D printable version of it. ▶ this video link
I'm sure you've seen this already, but if not: ▶ this video A 3:1 scale replica of the Curta, 3D printed.
Marcus Wu designed, 3D-printed, and assembled a 3x scale working Curta calculator. He shared his models and progress on Thingverse at link His YouTube channel includes many videos of the development, assembly, and operation of his calculator. Watch a short demonstration at link Adam Savage commissioned Marcus to build a copy. Adam unboxes his 3D-printed Curta on YouTube at ▶ this video
