3d Printed Curve Former. Made to help make rolling ball sculptures but would be useful for anyone needing to create consistent curves in wire up to 3mm. This design has been tested with copper and aluminum. This is a parametric design so that you can automatically adjust the spacing between levels with one value change. The default is made for a 12mm ball and the spacing is 10.5mm.

The resolution does not matter much, but there does need to be substantial infil to allow enough clamping force without deformation.
