Design Notes

Cavity vs core draft:

Twice as much draft angle is recommended for inside walls or surfaces as for outside walls or surfaces. This is because the alloy solidifies and shrinks onto the features that form the inside surface and away from the features that form the outside surfaces.
-> Cores: 2 Degrees
-> Cavity: 1/2 Degree
