SB3A Brace Plug

This is a removable reinforcement plug / filler that inserts into the SB3A brace for firearms to keep the rubber bands from deforming when in "Storage"

The stock brace velcro strap holds the plug in place creating a very ridged brace.

Firearms generally get moved in HOT cars. PLA can deform in a hot car so I suggest PETG or ABS or other higher temp plastics
