Star Lord's Quad Blasters from Guardians of the Galaxy. My own work based on movie props photos as accurate as I could. Dimensions are about movie size, fits into L hands (about average men's hand).

Star Lord uses two blasters - don't forget to mirror the handle. :)

Update 24. 9. 2019 - uploaded new combined STL, which can be directly opened in slicers.

Print instructions

Model file is not provided as print-ready. Separate individual parts (click Split to Objects/Split to Parts buttons in PrusaSlicer or similar function in your favorite slicer) and cut/rotate it depending on your material and printer needs.

Handle flaps will probably need supports (I used them). And, depending on your orientation, barrel holes in top and bottom body too.

Some parts get assembled easier after a bit of sanding.

Print mesh flat separately, heat it by a heat gun, shape it and trim excess.

I used some wire pieces to help me center few parts, especially barrels, but not everywhere is centering necessary.
