You have small kids? Do they like vending machines and playing with cardboard boxes? I have a very quick print for you to have an afternoon of fun…

Get a cardboard box, cut in holes and stick a coin slots and/or slot for bills in. Also cut in a flap to dispense the purchased goods (toys, pens, chocolate, whatever). If you are fancy, print a second coin slot and put it in upside-down to return coins.

Have one kid behind the box to select toys to dispense. The other is in front and feeds in money. The coin slots are perfect for e.g. poker chips. Print some bills or let your kids draw some.

Have fun!
