I printed the Nuke Lamp by MaximFilms (http://www.thingiverse.com/thing:19478) in 50% scale and wanted it to have an inside LED with on/off switch. So I made a simple stand for the Nuke Lamp, where you can put a battery. Switch on by sticking the LED wires in the stand. Switch off by sticking the wires in the stand, but the other way around. Enjoy!Print the nuke_light_stand with your desired infill (I used 20%, which still was plenty). Use at least 2 perimeters or you most likely will see the battery when printing with a bright material. Fold a little paper spring, put it in one half of the stand, put the battery above it, close the stand and put some tape around it. Done. Alternatively, you can print nuke_light_stand_left_right_connect two times and maybe omit the tape. But I must warn you, I did not try this, it was just an idea. It might be to fragile. The holes have 2mm radius and the cylinders have 1.9mm. Feel free to change the pk2 files, if you need a different size or want to change something.
