Makers' Marks: Physical Markup for Designing and Fabricating Functional Objects
summary
System lets makers sculpt real shapes, stick sticker annotations for parts, scan the object (desktop 3D scanner or photogrammetry), detect marks with SIFT keypoints + RANSAC, remap 2D marks into 3D, align parts by pushing them along normals, and synthesize clearance and mounting models (bosses or lips) to produce an STL for printing. Prototypes include a game controller, hinged alarm box, animated left-shark with servo, and a baby-monitor toy. It runs but stickers limit precision and scans need expert cleanup; surprising price benchmark mentioned: $799.99.
