Snap-Together Mini Minecraft Jack-O-Lantern with integrated LED

thingiverse

Happy Halloween!!!!! This is a quarter-sized version of my previous Minecraft Jack O'Lantern, now with integrated LED and CR2032 battery and 3D printed button controls that print without support! You can print either with a hole in the stump or without it, and you'll probably want to print one of my Flame LED Diffusers as well. The LEDs I'm using have an integrated candle flicker chip and 29mm long leads, so they can be bent around and used as contacts for the battery. If you'd like to use it as a keychain, you can print with the stump having a hole and use some common ball chains found in hobby stores or here: http://amzn.com/B072N6T26K I put together a YouTube video explaining the assembly, which involves sanding and fitting parts together. You can find it here: https://www.youtube.com/watch?v=9dpTfo4SHSE I'm using a Monoprice Maker Select Mini with good tolerances, and I'm able to fit the parts of this print together with just a little sanding or shaving to remove excess material. If your printer is over-extruding, you may need to do more sanding. Also, be sure to have some crazy glue on hand, as there's a risk of parts breaking off, particularly the bottom corners of the top piece. PLA can be unforgiving. My go-to filament for this design has been Hatchbox Orange with the buttons in GO-3D glow-in-the-dark green, but I've also done a few pumpkins with Proto-Pasta Tangerine Orange Metallic Gold HTPLA. You'll also see some pumpkins that are green – those were made from an old spool of filament sold as "glow-in-the-dark" years ago, but it didn't work well until I paired it with a 395nm UV LED for a spooky effect.
