This is a remix and modification of the Bergman's excellent 1-100 scale M3 Half Track series.
I upscaled the M15 AA half track to 1/56th - 28mm scale. I cut the gun pack out and modeled it to print separately, which makes for a much cleaner print.
I cleaned the lines of the hull, removing the driver figure, and cleaning up the cab.
when printed, simply glue the gun pack back into the turret.
BTW I use paint stripper to fasten the pieces together. The jelly like stripper, which contained methelyne chloride; is a great glue for PLA. It is very thick; akin to regular model cement, which itself will not work on PLA. Alternatively, you can use CA, but it does not give much time to reposition any pieces.
This model is a great option for any Allied Bolt Action player who is getting hammered on the game table by Axis light auto cannons. This model (in the US Army book) gives you a heavy auto cannon and two heavy HMGs... a nice to have option.
