The general idea is fabric patterns would be printed in TPU & the TPU would be folded like fabric.  Unlike a fabric, TPU sheets can have vertical elements.  It  would have EVA panels sandwiched between voronoi patterned TPU sheets.  The simplest camera bag is a box.  The edges of the box could have vertical elements of the TPU fabric.  The vertical elements could be where different sides of the box or different sides of the EVA sandwich join.  The mane limitation is the size of the print bed.  The box couldn't be printed in 1 piece.  Each side would have to be a standalone panel.  It might have to use solvents to bond the TPU sheets.
