Mechanical calculator "Pascaline" (modular design)
thingiverse
This remix takes its cues from José Campos' Mechanical Calculator project with a modular design twist. Check out the original on PrusaPrinters: https://www.prusaprinters.org/prints/28807-mechanical-calculator-modular-design. To give it a fresh look, I made some cosmetic tweaks and swapped out some gears for springs to enhance its performance. Make sure to pay attention to how all the parts align. For those interested in the history behind this design, here's what José had to say: "This project is based on Pascal's famous calculator from 1642 (https://en.wikipedia.org/wiki/Pascal%27s_calculator). For a detailed explanation of how it works, check out this YouTube video (https://www.youtube.com/watch?v=3h71HAJWnVU&t=260s). The design has been simplified and adapted for FDM printing. A key adaptation is the modular design, which allows you to build modules to increase the calculator's size and enable larger operations. However, due to its asymmetrical mechanism, each module must be built in an alternating pattern of A-B-A-B... to perform the "carry operation" correctly.
