This is a 28mm scale model of the American M16 and M17 Motor Gun Carriage. These was supplied to other allied nations, and was used post war in Korea and many “bush wars”.
I started with my previous file of the M-5 half track, and
- squared off the back to resemble the M-3 half track model
- created “cut outs” on the side and rear of the H/T which allowed for weapon traverse
- added detail and hinges for the drop side flaps on the sides and rear
- raised the floor on the back of the half track
- added storage boxes to rear exterior
- created the seven piece gun turret (please see the pic on assembly notes)
- added “bolt” detail to the hull
I added a screen shot of Tinkercad showing how the “turret” and guns assemble. It is mirrored for the other side
Use 0.1 mm “fine” for all printing EXCEPT the “gun pack”; use “extra fine” – 0.06mm on Cura – for the gun pack.
I was happy with the design but not the test print. I had run out of my normal grey PLA+ and had to use a black PLA… which stringed an incredible amount and was difficult to clean off because it was black and hard to see… until it had been painted… lesson learned; the black PLA has been demoted for use in terrain pieces only.
Also, it was pointed out that my choice of model nationality is in error, only the M17, based on the later M-5, was supplied to the Soviets. This model with have to soldier on as a historical enigma. I wanted to test print the M3 Hull version, hence the M16, as it was produced in the highest numbers and saw the broadest service among nations. After I posted this file, I realized it would not be difficult to create the M17, so any Red Army player can have a historically correct. I still needed to test print the M3 hull, so one M16 is clearly going to sneak onto the gaming table in Red Army livery.
The “turret” fits on the protrusion in the H/T bed, and pivot well.
