Luv's Blaster (Blade Runner 2049)

I have modified all of the parts based on a three photos of the actual prop and the interview with the original builder and Adam Savage on Youtube. 

Added routing for LEDS (2No. Red 1 No. Green 3mm and 2No. white 5mm, 1s battery, TP4056 battery charger and microswitch). It is a very tight fit and may require fettling to get everything to fit

6No. 3mm diameter magnets for the back cover door

Based on the interview I have added movement to the barrels, they are mechanically linked to the trigger, with a spring to provide tension fixed to the barrel cover. You will need to try different sizes and strengths to find one that returns the barrel and trigger to the original position but start with a 6.5x22mm or 5x20mm extendable spring

Some m3 and m2.5 machine screws of various lengths

Photos will hopefully explain a little of the build order. There will be a lot of fettling/sanding trial and error to get this right.

Note the orientation of the microswitch.
