Japanese erasers and keychain sets have been popular with kids for years. These items can also serve as 3D learning tools, especially the erasers that can be disassembled into basic shapes for computer modeling. Once reconstructed via 3D printing, these models make great keepsakes. Joinery is a valuable skill for young inventors to develop, and designing multi-piece objects provides interesting challenges whether assembled or as separate printed parts. Such creations, along with others on Thingiverse, are useful exercises for anyone learning 3D modeling. Bob Krause, Inventor Studios, Berkeley, CA.
