LED glow skull lantern

thingiverse

First of all, there are several excellent variations on this same concept. This one is fairly simple - just an on/off switch that controls 4 UV LEDs which give the skull a nice eerie glow when on, and charge the glow-in-the-dark plastic for continued glowing when off. The model that is uploaded is slightly different than the one pictured because I originally had placed the battery holder without realizing that the placement of the on/off switch made it impossible to remove the battery! So the uploaded STL has the battery holder rotated so that you can remove it. I used these push-buttons https://tinyurl.com/y2ozwcrl but needed an extender for the button to reach through the housing so there is a file for that included as well. I imagine a person carrying it around on Halloween which is why it's in the 'costume' category.
