Josef Průša saw last week’s post about choosing a silicone for casting soft button arrays and pointed me to his printable mold for such arrays on Thingiverse. The model was produced in Clifford Wolf’s awesome OpenSCAD 3D modeling package, and the .scad script is available for download with the Thing. It has been parametrized to produce molds of button arrays having any number of rows and columns–all you have to do is change two values. The individual buttons are sized to match the SparkFun 2×2 button pad used on the monome, and also include backside recesses for LEDs.
