Directions - put your inclusions in, seal the two sides (we use super glue or UV resin), use the hole to fill it with your liquid core mixture of choice and finally seal off the hole. Then you are ready to pop them into your numbered master molds. We designed these 2mm smaller than our standard masters for a snug fit.
Molding suggestions - mold each half separately for a two part mold and use a 10-15 shore-hardness silicone. Cast like a regular master dice, using one of the flat faces to stick down to your tape.
If you need different sizing to fit your current masters we can absolutely do that, send us a message and we would be more than happy to adjust accordingly.
These designs were inspired by Pixel Raptor Designs, the original creator of 3D printed hollow core dice.
