Re: Star Lord Map Gun - WIP
Looking good so far.
Is that filler-primer or regular primer? You'll have a much faster result with the former. Also, any reason why you put the power switch that far forward? The rearward rectangle was made specifically to house a circuit-breaker, either by adding a pin to hinge it (in that little indentation) or just by using the flex of the plastic to click a panel switch.
This is kinda how I see it working:
Note that this diagram shows BOTH possible variants. You either hinge the plate and add a spring OR you glue the back part of the plate and use the natural flex of the plastic to depress the circuit. If you do the latter, you will need a panel switch with VERY little travel, such as this:

You should also position the switch so that it just barely touches the underside of the plate is "off" position. I did this with my Dredd lawgiver, hiding two switches underneath the serial number plate on the side. This allows me to control ammo and firing modes on the gun while not having any visible switches.
