Directly printable project. Please, note you are suggested to print with low speed settings and consider to use vinilic glue to fix the components better, but not between part 11-8 and 2-3. Parts 11-8 and 2-3 formed two axis of rotation to move the anti-aircraft. Printing instruction: Print one piece fore every component (file). Rather, print Pom pom 1 x 2, Pom pom 5 x 2, Pom pom 7 x 8. Enjoy!
