Batman Gun Arrow
thingiverse
This is a spare arrow for the arrow gun that came with a Batman toy car. The arrows are quite small and can easily be misplaced, so this is a handy backup. It’s modelled in OpenSCAD for easy adjustments, depending on printer tolerances. The slit parameter can be used to configure with how much force the arrow should be shot. A higher value will compress the spring more and shoot it with higher force. 14mm is quite close to the original and I have found that values between 12-17mm will work. https://github.com/emilerl/3D-models/tree/master/Batman%20Gun%20Arrow
