I wanted a coin dispenser that I could keep in the center console of my Jeep Wrangler. I was inspired by https://www.thingiverse.com/thing:2275395.
Some of my fingertips have been amputated and so I do not have much dexterity to pick up coins that are laying flat. With this US coin dispenser, I can slide the coins in/out from either side. I have used it a a drive thru hamburger joint and am very satisfied with the functionality.
I used #4 pan head sheet metal screws that I got from Home Depot. You could use 1/2" - 1" length screws.
I used 23/64" x 1-3/8" compression springs from Harbor Freight.
Holds about - 8 quarters, 8 nickles, 10 dimes, 10 pennies
