Crossbow
A simple to build and assemble crossbow. Perfect for terrorizing family, friends, pets and co-workers.
Fits in the hand nicely, yet not too big. A springy trigger makes this crossbow a pleasure to use.
All parts are printed, except for 2 rubber bands.

NOTE: I've updated the Handle_Cover so it's not as tight.
Instructions
Print 1 of each item (Arrow optional).
I use Slicer with the following settings:
Perimeters = 3
Top/Bottom layers = 2
Layer height = 0.2mm
Infill = 30%
2 Rubber bands required. A small one (approx 20mm diameter) for the springy trigger, a larger one (approx 50mm diameter) for the bow.
First insert the Firing_Lever with small rubberband into handle, then slide in the Trigger. Confirm mechanism is smooth - trim/sand as necessary (depends on your printer quality).
Second, wrap larger rubber band around bow, then attach to handle.
Lastly, push the handle_cover over the mechanism. It should be a tight fit which holds itself in place.
You're good to go!
