  •  Measurements
    • floor to bottom of wheels - 4 in
    • floor to top of wheels - 8 in
    • center of hex shaft axle to center of hex shaft axle - 15 5/8 in
    • center of hex to backstop - 7 1/4 in

Cargo losing air
Cargo that was left out for 36 hours shrunk from 13" to 12.73" in diameter, which is roughly .0075" per hour and .18" per day. Cargo needs to be between 12.5" and 13.5". Expect more shrinking when the ball is used.
