Rib Machine
draw one working edge, then print the pottery tool your hand is missing
A pottery rib begins as a small argument between the hand and the clay: this curve, at this angle, with this much give. Rib Machine turns that argument into a printable tool.
Draw one side of a square from top-middle to bottom-middle. The machine looks for lines, arcs, and corners inside the gesture, then rounds and smooths the result without sanding away its character. The other side stays steady in the hand.
The finished form is not only a picture. It is a watertight 3D body with a fine working edge, palm rounding, and thumb relief — ready to download as STL or GLB.
Use it: draw slowly from the top marker to the bottom marker, tune the fit, then open full screen to download the mesh. PETG is the friendly first print.
