This is a configurable soroban / abacus.
You can configure/customize it using the free CAD program OpenSCAD.
It prints in one go without any supports. Note that it has to be turned around after printing for use (the feet will stick upwards to be printable)
The default soroban has 4 balls of value 1 and one ball of value 5 on each rod. It has 13 rods.
In case you print it, send me a nice picture please so i can update the title picture here.
Have fun!
