A personal design project: a more elegant repository for the paper referral slips passed around at BNI (Business Networking International) meetings, complete with a custom engraving of the “Gateway” chapter, where I was a former member and Chapter Vice-President in Singapore. I envisioned it CNC-machined in a hardwood such as chestnut or walnut, and produced this prototype by 3D printing from an Autodesk Inventor CAD model.
