Binary Abacus Counter | Educational Tool

Binary Abacus

An abacus with binary pieces that can rotate to quickly swap between 0 and 1. 
It can express 8 bit registers, and has 3 rows ( so you need to print 24 Of the Bits ). Also Use the divider to keep your additions neat.
There are two different Lids, one with the binary base headings and a plain one. 
I included a plain bit if you would like to edit the model or put your own number in a better font or whatever.

The assembly is pretty simple. Print the base and 24 bits and the optional divider, put the bits on the base then put any of the lid designs on as you wish.
You can of course use the photo as a reference, (real print uploading soon, waiting for it to print).

Id recommend printing at 50% scale, if you cant print the giant 100% size.

Let me know if there is any issues, will try to help asap.
