			== Motor placement ==
			Z motor is placed near top of printer so that we can scale
			in Z-direction by giving frame "legs" and mount a longer
			Z-axis actuator without imposing a new motor position for Z motor.

			The following requirements lists have been compiled using parts of [https://en.wikipedia.org/wiki/Axiomatic_design Axiomatic Design Methodology]. The main point we've borrowed can be summarized like this:
			We strive towards creating lower triangular matrix mappings (preferably diagonal matrices) between the four domains:

			<big><font face="bookman">Customer needs ↔ Functional requirements ↔ Design parameters ↔ Process variables</font></big>

	~~:<big><font face=~~"~~bookman~~"~~>Customer~~ needs ~~↔ Functional~~ requirements ~~↔ Design parameters ↔ Process variables~~<~~/font~~></~~big~~>		The formulation "striving towards diagonal matrix mappings" may be formulated more verbosely as
			Try to organize a list (vector) of customer needs such that they are mutually independent.
			Try to make each functional requirement address exactly one customer need.
			Try to organize a list of functional requirements such that they are mutually independent.
			Try to make each design parameter affect the fulfillment of exactly one functional requirement.
			Etc...

			There's a special emphasis on the mutual independence of functional requirements within the axiomatic design methodology. The principle is regarded so useful and important that it is dubbed <i>Design axiom 1</i>.
