With regards to raising the anchors to eliminate Z axis force- if the frame can be flexed by the belts’ tension, then any arrangement where the anchors are attached to the frame will transfer the same net force to the frame- and the greater the anchor offset, the greater the moment arm- more leverage, more force on that point on the frame.
see Possible super-simple frame - #39 by bar for a
picture of what I’m talking about, that arrangement avoids the lifting force on
the frame.
