Soroban

Soroban The soroban is a traditional Japanese abacus developed in Japan. It is directly derived from the ancient Chinese suanpan, which was imported to Japan in the 14th century.[1][nb 1] Like the suanpan, the soroban continues to be used today despite the widespread availability of affordable and practical electronic calculators. Design This design was created using openscad. The rods that hold the beads are made from 1.75 mm filament. Assembly To assemble the soroban, feed a short length of filament through the frame and add the beads one by one. Once complete, cut the filament to length and secure it with a blob of glue. Tweaks It may be necessary to adjust the hole size of the beads based on how accurate your 3D printer is.
