It is easy to squeezed the sides of 1/8" tubing, so such a thin wall should in general be avoided. If using thin walled tubing, use a 3" or large washer, ~2x as thick as the tubing, to spread out clamping force.

			==Structure: XYZ Construction==
			*Whenever building a device, make the frame structural by assuring that bolting is done along 3 axes at each corner. This allows the construction to be a space-frame construction with all corners having equivalent strength.
			==Modular Wheel Units==
			*Whenever attaching modular wheel units to frames, attach over 12" of space to prevent twisting of tubes under heavy loads.
