(So diy'ers could make one)?
I wonder what could be used for the belt? This structure actually looks easier to build and seems more sturdy.

As far as ease of build, I suspect that’s not quite the case. The main thing I would worry about is the belt flexing under the print head. If you think about it, the nozzle only moves across the bed in a straight line, left to right. To print an object with a Y dimension you need to move the belt forward and back and depending on how you set up the line on which things are printed if there is flex there you won’t get bed adhesion. You could use the treadmill belt material coated with something that can be printed on. Or whatever belt sander belts are made of before the abrasive is glued on.
A one-way belt also wouldn't have as much problems with adhesion, or backlash that you mentioned with a two-way belt.
Also, the nozzle moves in the Z direction (not just x). Actually the Z direction is really a little z and a little y.
The head can not travel in a plane parallel to the base plate, so it can't use paths calculated for a regular flat primer.
