About this 3D model
Quake inspired rocket launcher 3D model, ready for printing. I scaled everything to fit standart 20x20x20 printer, it is 83cm(32.5 inches) long. Use super glue or epoxy to assemble. Some parts need supports. Best way to print big body pieces is to set 5% infill overall and tweak infill% where it's needed(for the last top layers for example). Print one alignment pin first to check how it fits, most probably you will need to make adjustments to it, tolerances on my printer could be different from yours.
