Here's a video of it in action... https://www.youtube.com/watch?v=Rwvbkn8xL6A&feature=youtu.be Here's a group I made for my LED lights and things, if you like my LED designs, join the group and you'll be updated as I upload new ones... I plan on making a lot more logos just like this. So if you have and suggestions, please tell me and I'll make it. http://www.thingiverse.com/groups/things-with-leds/things This is a extruded LED Makerbot logo I printed on my dual extruder... I took a JPEG of the Makerbot logo and traced it in Solidworks... I then extruded and filleted the logo and saved it as its own STL to be used in dual extrusion... I then designed a plate around the logo, added holes for screws and save that as its own STL... Lastly, I design a shell to go around the plate and logo, 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 logo... 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... I've also made the following logo's, designs for LED hookup...
