Gatling Gun in parts

after trying to print about half a dozen of different Gatlings, i gave up.
(my printer gave out some interesting pieces of modern art)

so i cut up the Gatling from Autodesk 123D.
now even my printer is able to do the job(s).

set includes.
the entire Gatling (for those with good printers)
the Carriage (print with support)
the Barrels (print with support)
the Magazine
two different wheels (well, three...)
the original "rad" (print with support or standing)
and the revised "rad" to print laying flat on the bed.
(the revised "rad 2" has zero overhang on the underside)

do i need to mention, that two wheels of the same kind let the model look nicer?

for scale 1:32 (more or less) i print the parts at 350%
(but to be honest, i think, they get too large for 1:32)
