Papercraft Workshop
Unfold a low-poly OBJ or STL into printable paper pieces with glue tabs, matching edge labels, fold directions and a real assembly reference.
How we build a check
This workbench processes supported inputs locally. We test calculations, file structure and generated artifacts using independent readers or known fixtures where available. The example runs the same processing path as a supplied input; it does not stand in for checking your own result.
Editorial responsibility
