This is a crossbow bolt retention. For holding the crossbow bolt down to prevent miss fires. I suggest printing in a flexible filament such as TPU so it can flex and the bolt can be put underneath it and held with tension. Scaling is required depending on you crossbow. The whole in the back is a spot for a nail or a screw. Disclaimer this has not been printed or tested before. Hope you find it useful.
