Penny Catapult

thingiverse

Print with no support and 35% infill to achieve maximum stability. To secure the fulcrum, insert a nail or straighten a coathanger wire through the holes at the top of the base and center of the arm. Next, fill in the side of the base with hot glue to create a sturdy foundation. Secure a rubber band by threading it through the hole on the lower part of the base and the hole on the end of the arm. The bucket features a precision-cut slot that allows you to place a penny upright inside, enabling it to roll freely when released. Alternatively, you can lay a penny flat in the bucket for added versatility. Bottle caps prove to be an excellent ammunition choice due to their shape and size.
