simple catapult.
You may note a bump on the front that is to hold one of the loops of the rubberband for lower power shooting.
you might also notice a notch cut into the track, when you learn the trick of it you can reliably hook the penny carriage into the track, until you are ready to fire. slight downward pressure launches the penny.
prints well at low quality with no supports
