Quarter counter

thingiverse

We operate rental properties with coin-operated laundry machines - lots of quarters need to be counted and wrapped. I tested most local coin counters but found that the best one wasn't working very well - it was too thin and fragile. So, like everyone else, I decided to design my own counter. This is for quarters only, holding 40 of them, and I wanted the printed item to weigh at least 30 grams so it's easy to weigh to check the count - it should come out to 255-257 grams. When the right number of quarters are loaded, adding one more will cause the tube to slide back out with a simple push on the top. The slots allow you to verify if the count is correct. After loading the tube and tapping it a bit, the topmost quarter should be very close to the top of the slot but not over. If the count is low, there will be room for one more quarter. I also wanted the tube to be wide enough so that you can slide the paper sleeve all the way down around the quarters. It's a bit tight with some sleeves, but it does work. You can push the stack up into the sleeve just a little and fold down the top, then invert the tube and pull the sleeve out to close off the other end. I hope you find this as useful as I have!
