First I modeled the pieces in CAD.
Next I 3D printed them jawns
After a lot of sanding I put the pieces into clay and made plastic walls for my mold.
Next I poured Oomoo 30 silicone rubber for the first part of my mold
Next, I need to make the second part of the mold by taking the clay out and pouring more Oomoo 30. Then I will be able to pour plastic and make my parts.
