This is a stage property for Cosplayers, no real functions. I restored the looking of it as far as possible.

(1) For the plate and grip, and barrels, Black, gray/sliver PETG is recommended;
(2) Battery cases is ready for 2 of 18650 cells;
(3) 2 segment of filament is used for simulating the wires;
(4) Transparent PETG is recommended for the trigers;
(5) I used yellow tapes to decorate the looking of wood, because my wallet is empty for another spool of yellow filament :(

I print with 0.4 nozzle, 0.15mm layer height, 20% infill.

All u need is a roll of electrical tape, have fun!
