About this 3D model

I really like the "Duke" gun family in Borderlands and when i saw one with two exhausts, i just had to model one for 3d printing^^ Its about 33 cm long and consists of 50 parts. This is not an easy print! there are a lot of parts und multiple parts are awkward to print, so a good understanding of your printer would be beneficial. The files marked with an "(X2)" have to be printed twice.
