Parametric open-face mold generator for OpenSCAD

thingiverse

Create open-face molds from STL models with OpenSCAD scripts. Positive script combines model with a flat base, negative subtracts it, forming an indentation. Ideal for ice-cube trays. Includes sample files and blog post for inspiration. Prepare low polygon count STL models, avoid undercuts or overhangs. Download .scad file, update parameters, compile, and export as STL. Mold parameters include size and rounded corners; wall parameters toggle walls and adjust thickness/height. Removable wall option available in positive script for easier demolding. Consider using removable walls for tall molds or stubborn casting materials; secure with modelling clay.
