This is my daily design 2.
Enjoy a credit-card sized working re-usable catapult.
V1 and V2 have slight differences, depending on your filament type one would work better than the other.
You also need a rubber band, both sides in the small perks on the two sides and through the marks above the spoon.
The U shaped piece is to be bent to 90 degrees and hold by the removable piece between the perks.
The circle on top of the spoon is for you to hold it with your finger.
