Jan's Invoice Number Tracker

thingiverse

My wife is kinda old school when it comes to her personal business. She wanted a simple, non-digital way to track the customer invoices she was issuing, so I gave it some thought (okay, not much - I'd seem just the thing a few days before), and whipped this up for her. Four wheels to track numbers 0 to 9999. Should you want larger numbers, the frame and post are easily remixed to a accommodate more wheels. The wheels and frame are pegged to keep the numbers locked in place.
