3 part mold for casting fire cement skulls

thingiverse

I made this 3 part mold for casting fire pit skulls out of refractory cement. I recommend clear coating the pla parts to seal before use and spray with mold release before each casting. I used inches as the units while designing so for some slicers you might need to scale up 2540% if it interprets as mm. The spout can be printed twice and superglued on in 2 parts (although it isn't necessary) I also include the model of the skull itself but you don't need to print this. To cast mix and poor in refractory cement. Make sure you tamp the mixture in well or use a vibrator to avoid bubbles. instructional video here: https://youtu.be/NNk09C9IiSk
