What happens if you run out of batteries during quarantine and you can't sum or subtract big numbers? Here is the solution!
This is a design based on the famous "Pascaline", which was invented by Pascal in 1642 (https://en.wikipedia.org/wiki/Pascal%27s_calculator). Here you will find a detailed explanation as to how it works: https://www.youtube.com/watch?v=3h71HAJWnVU&t=260s
The 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.
Files:
group_a.3mf - all internal parts of a "Module A"
group_b.3mf - all internal parts of a "Module B"
0_base.stl - base (generic) for modules
0_lid_side.stl - side lid to cover mechanisms
0_lid.stl - upper lid to show only "results"
4_connector-stl - connector piece to join modules
