Created a negative casting mold of the “Fantasy Dildo” model.  This mold allows you to cast a model of the original dildo.  I cast directly into the mold using platinum silicone and it turned out really well.  No release or coating agents used.

For some tips on casting 3d printed sex toys, check out this post from Billie Ruben.  She recommends using beeswax to coat the mold and smooth the surface, but I had issues with the beeswax inhibiting the cure of the silicone.  Maybe other waxes or coatings will work better.  I'm still experimenting.

Mold uses 3/16" dowels as alignment pins.

If you print this model, please share your makes and like this post.  Thank you for checking out my models!
