foldable box 3d model

It's a die-cut template for a foldable box where: The center is a solid base, surrounded by four side panels connected at the red fold lines. The blue ovals are slots cut into the side panels. The yellow triangles are support stands that slide into those slots, acting as braces to keep each side panel upright and rigid rather than flopping flat. Each triangle corresponds to the slot nearest to it. So when assembled, you fold up the sides and insert the triangular stands into the slots to lock everything in place. build the box where panels are upright and rigid with the connected triangle braces in their slots
