Thingiverse user Steve Thone has come up with his own version of the mini-crossbow, inspired by the popular mini-crossbow currently being made by many different users with items like popsicles and bottlecaps. Thone 3D printed a mini-crossbow using 3D printed parts for the apparatus, a screw to hold in the working trigger, hair clips for a bow, and Q-tips for arrows.
