I was trying to show the concept quickly (ironicly, i was trying to improve on
your design, but i couldn't rmember where i saw it, so i couldn't give
credit!). I had intended to do the math on a non-snot version for the exact
strength reason you mention. also, maybe a part #3749-"Technic Axle Pin" could
be used instead of pins on four of the male parts, to reduce friction & keep
rotational stability.
