Here's a video of it in action...

This is a extruded LED Punisher I printed on my dual extruder... I took a JPEG of the Punisher and traced it in Solidworks... I then extruded and filleted the Punisher and saved it as its own STL to be used in dual extrusion... I then designed a plate around the Punisher, added holes for screws and save that as its own STL... Lastly, I design a shell to go around the plate and Punisher, the shell has aligned screw holes so it can be fastened to the plate...

I then printed the shell in regular ole black PLA on my Rep 2... And I did the dual extrusion using the same black PLA for the plate and I used Bendlay (link below) to print the Punisher... I used Bendlay because it is extremely translucent (91% of light passes through)...

I then hooked up an RGB LED strip, wrapped it around the inner shell and hooked it up to an IR receiver so it can be controlled with a remote...
