Summer Smith's Laser gun from Rick & Morty episode Total Rickall.
This is not an accurate version but altered to fit in a hand :)
Made so it can fit into Creality CR-10 as one object but also in pieces for smaller printers.
Still haven't printed actual 1:1 version but smaller one was made without any problems.
