Custom Ring Gasket Mold SCAD

thingiverse

This is a customizable mold to help you make custom gasket rings. It is generated in 2 parts, so you have to edit the SCAD file to generate the second part. Look up cornstarch silicon oogoo. Add some food coloring for color. I think you're better off mixing it in a sandwich bag. I think I did a ~50/50 mix by volume. It's very messy. Lubricate your mold, fill up the mold, smash it together and clamp it as you see fit. It'll probably take you a few times to figure it out, and you'll have to clean up the gasket after it sets.
