yeah i was thinking screws and trapped nuts on the orange pieces but didn't get around to modeling it in. Those trapped nuts can be a PITA to design right. the motor pieces probably need it too, at least on one of the arms (but adding it to one of the arms will print it on both, since it's the same file. not that that's a problem).
Another idea is just small holes that you tap, and forget the trapped nuts. much easier to print, and the screws don't have to be *that* tight to keep the rods from sliding.
Plus, the motor can slide to tighten the x axis belt, so you don't need a tensioner on the carriage.
