This is my take on the popular Popsicle stick mini crossbow seen on the web. I upgraded it to use an actual trigger though.
1/18/15 - Added a flat top version for easier printing. (I have not test printed this version myself though.)
The crossbow was printed upside down (handle pointing up) with minimal supports. (Sorry, one of these days I'll figure out how to upload them the right way.) The trigger is held in place with a 2/56" x 1/2" screw and it uses metal hair clips for the bow and Q-tips for the crossbow bolts (arrows). The center portion of the hair clip is removed by just bending it back and forth a few times to snap it off and then the clips are just slid into the cut outs. (you can glue them in if needed.) When attaching the string pre-load the bows a bit before tying the final knot. (but don't over do it) Enjoy and play safe.
