mini Crossbow

this is a very simple little crossbow, that uses 2 Ballpoint Pen Springs to Launch a Toothpick.

these Springs do not tend to be very Strong and thus the Projectile is basically safe.
you shouldnt aim it at People, Animals or breakable things though obviosly.

for me it shoots about 2 or 3m ( almost 10 ft) when shot horizontally from a height of 1m (about 3ft)

besides the Printed Parts it needs a piece of String and something to use as Pins for the Trigger mechanism and the Two Rollers.
i used 1,6mm Nails i clipped to the right length.

Have Fun with it
