You can get cheap Nails that work great to hold a bow target face but those usually lack a comfy way to get the nails out.
You can get nails like those for 10 cent per piece: https://amzn.to/43tDKTk
This model is made to wrap around the nail and make it the perfect bow target face pin for a few cents more. The tolerance of the nails is usually not very accurate.
To ensure a perfect fit, the model has been made tight. If you run into issue fitting the nail into the handle, you may need to shave the plastic of the nails, especially if the surfaces look a little round.
I strongly suggest using the provided gcode as the slicing was optimize for costs, print time and mecaniocal resistance (ie the base has low % infill but the handle has more infill).
