A crossbow with a scope. The main body and the trigger is print-in-place. One of the pictures shows how a rubber band makes the trigger functional. Simply snap the arrow retention/scope in place and attach the left/right limbs with short M4 screws and bolts and you have yourself a functional crossbow.
I used the elastic string that came with the broken wooden one that came with the one I bought. I believe a stretched-out TPU might serve the same purpose.
I'd print the arrow tips in TPU to avoid injuries/damage to precious stuff. I also included 5 different arrow patterns. No support needed for any of the parts.
