About this model

Place this safety flag in your gun bore when not in use to eliminate the chance of a misfire. Most Gun Clubs require them at their Ranges. Let me know if you want custom text & I will create it (must be brief!!!) - I haven't figured out how to make it parametric yet as I am new to 3D printing. Also, use a bright color, not black like I did!
