Simple Toy Crossbow

This is a simple toy crossbow I made with Tinkercad.

Print it as it is, then insert the T-shape's end into the other part.

Then, tie a rubber band around the posts, and thread the rubber band through the small hole in the T-shape before you tie it to the second post.

Once it is assembled, put a marble or other projectile in front of the crossbow, pull back on the handle, and release. The T should strike the marble, sending your projectile forward.
