Napier's bones is an abacus created by John Napier. It can be used practically for multiplication, division and square root operations. Napier published this work under the name Rabdology at the end of 1617 in Edinburgh, Scotland.
I prepared an easy to print and a storage box for the sticks.
I would be happy if those who have printed it share their comments.
