This is a Soroban Abacus, an abacus that is widely used for accurate decimal calculations.
To assemble this, please print both parts with the hinge facing upwards, and turn off supports, as they are generally not needed.
In order to add the beads, you will need to cut off some raw filament, and thread it through the holes and the beads to keep it together. (Refer to the image)
The hinge for the folding aspect uses the same idea, using a piece of raw filament for the center of the hinge.
This is my first self-designed model that I have posed on Printables, Enjoy!
For use of the abacus, I found this really nice video that explains it very well. Please show support to the creator as well!
The author marked this model as their own original creation.
