Parametric two-part mold generator for OpenSCAD
Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
A set of parametric OpenSCAD scripts that generate ready-to-print two-part molds from arbitrary STL models.
These scripts can be used to generate either **square** (with or without rounded corners) or **circular** two-part molds and are fully parameterized to make it easy to adapt for your application.
Refer to the instructions below for some general tips, as well ideas for casting.
I have successfully made casts from these molds using wax, Knox gelatin, Oogoo and chocolate. If you have success with other casting media, please leave a comment!

If you really want to bring your molds and castings to the next level you can even try the ["lost ABS" (or lost PLA)](http://jason-webb.info/2012/11/lost-abs-experiment-with-3d-printed-objects-and-aluminum-casting/) process to turn it into…
