WebGate depth for an ABS part needs to be 75 percent of the part’s wall thickness. For a .100-inch-thick wall, the edge gate depth should be .075 inch. Since the land is based on the depth I follow the rule that the gate land should be half the gate depth, but not exceed .030 inch. In this case, I use the default dimension of .030 inch.
