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 (the latter is an engine mount plate from the Mobile Dimensions sawmill), but the fact remains that the latter could be simplified if design-for-fabrication were an objective.
