Nerf Tanto Bayonet

thingiverse

This is a combination of walterw's practice tanto combined with cameronlconnor's blank Nerf rail mount. I've found that it fits well on the more modern Nerf rails (Accustrike and Mega), whereas on Elite rails it clicks into place but has a small amount of wobble. Anything from the old n-strike line is a lot more hit and miss, as there didn't seem to be much of a standard to the rails used back then. The "blade" on this design is quite blunt and unlikely to do much damage, especially if a low infill is used. However, you may want to consider using a flexible filament or cutting a blade shape from foam board if you plan on using this around other people.
