### Development Notes ...
- while heat-setting M4 inserts in for the rollers, (1) there isn't *really* enough space to get the soldering iron in (without melting the adjacent pla) and (2) it's difficult to guarantee these go in straight. maybe use a press-in insert? / a hex nut ?
- long runs (beams) are not stiff ... try 1/8" waterjet stiffening folded members
- in the fullness of time, add an N23 size for torque-y applications like the CAT's bed: this is minimal overhead.
