SB3A Brace Plug

thingiverse

This is a vital accessory for firearms that prevents rubber bands from deforming when storing the SB3A brace. It's designed to insert into the SB3A brace and keep it secure. The stock brace velcro strap holds this plug firmly in place, creating a very stable brace system. When moving firearms in hot cars, it's essential to use higher temperature plastics like PETG or ABS, as PLA can deform under such conditions.
