Joe creates a 3D-printed Japanese-style abacus!
This prototype has five rods and is sized for adult hands. Besides printing the parts listed below, you will need five brass tubes, each 1/8 inch (or 3.175mm) diameter and five inches (or 127mm) long.
For permanently assembling the frame, you will need Weldon Acrylic Cement and a needle applicator; or cyanoacrylate glue.
