Mini 3D-printable crossbow

thingiverse

I created this mini crossbow purely for fun, allowing me to fire toothpicks with precision. The springs utilized in my design are sourced from a large spring found in an old wind-up clock that had snapped apart. I simply repurposed the wire lying nearby to craft the bow's mechanism. The arrows themselves are made from toothpicks. Measuring 55mm by 42mm and standing at a height of 12mm, this miniature crossbow is quite compact. Every component was printed using my trusty HE 3D Reprap Prusa I3 printer. The dimensions of the springs are roughly as follows: thickness - 0.5mm, width - 8mm, diameter - 35mm.
