Design for Fabrication

See an example of the engine mounting plate for the Power Cube.

The point is, the mounting plate is a 1/4" plate with some holes. Nothing else. Simple to fabricate with the minimum parts.

Compare this to this engine mount plate on another device, which is not so simple:

Note: that may be a bad example, since we are considering different functions, but the fact remains that the latter could be simplified if design-for-fabrication were an objective.
