About this 3D model

I purchased a used Nerf Fortnite Tactical Shotgun for my son without a rear ammo cover in the stock of the gun. Decided I could make one myself. If you're missing yours or it broke, this is a replacement that should fit perfectly. This is a print in place and no supports are needed. PRINT SETTINGS Resolution: 0.2 Infill: 25% Walls: 3
