Multiboard Generator (Parametric Fusion 360)

Work flow is as follows:

Modify → Change Parameters

Set desired width and height of multiboard.

A value of 1 for TopEdge and SideEdge will remove the respective diamonds from that edge.

If you're using fusions' built-in 3d print utility, select the entire multiboard component from the sidebar, instead of selecting individual bodies.

To prevent lag, this uses a rigid group instead of a boolean operation, but the resulting .stl is identical.
