#DIY #BACK_TO_SCHOOL Going back to school?? do your math in style with this 3D printed abacus. This is the only 3D printable Abacus file with RESET button on internet. I had never used abacus in my school but saw my few classmates use one. So I did a lot of research and took suggestions from my friends to learn how to use it before designing it. It took me more then a week to design it LOL. I have added RESET button which makes it different from other abacus 3D file available on internet. Reset button clears the calculation in fraction of second and saves time while performing fast calculations. Abacus is an ancient calculating device with many versions originated and used worldwide. This is a Japanese version Abacus with 1-4 bead system and 13 digits (13 columns) which is commonly used in schools worldwide. Abacus is an acronym which stands for Abundant Beads Addition Calculation Utility System. This file is easy to 3D print each part separately and assemble later. Required a metal spring with diameter 4 mm<D<10 mm and with height around 6 mm. Spring can be obtained from push button ball pen . NOTE : Super glue only non moving parts only after assembled.
