Custom model of Tony Stark's 'Mechanic Gun' from Iron Man 3. Provided as solid part and exploded with keys for printing on smaller machines. Modelled in a few hours from movie captures and the Hot Toys 1:6 accessory.

Printed with 0.2 and 0.3mm layer heights, 0.4mm walls, 10-15% infill and 3-4 top/bottom layers.

I have updated the exploded model file with better keying now that I have tested all the parts. I would recommend slicing two of the cylindrical parts (gas bottle and handle) in half in netfabb or a similar program for printing as, at least for me, the surfaces of the parts where support had been extruded came out quite rough.
