This is a fantastic modular calculator print from Davide on Prusa Printers:
This is a remix of the José Campos project, Mechanical calculator (modular design).
I made some cosmetic changes, and I completely replaced some gears, added springs, to improve the functioning. Pay attention to the alignment of the parts.
Reported below the explanation from his project:
This is a design based on the famous “Pascaline”, which was invented by Pascal in 1642.

https://www.youtube.com/watch?v=3h71HAJWnVU&t=260sThe design was simplified and adapted to FDM. One main adaptation is the modular design. With it you may build modules to increase the size of your calculator and thus enable larger operations. As the mechanism is asymmetrical, in order to perform the “carry operation”, the modules need to be build in a A-B-A-B… fashion.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
