Minecraft Ore Night Light

thingiverse

EDIT: I added a base for the cube with mounting posts for the Trinket and Neopixel boards, and updated the cube to include a cutout for the USB power. Use MinecraftOre_A_v2.stl with the original MinecraftOre_B.stl, plus MinecraftOre_Base_v2.stl. The base should pressure fit into the cube with no need for glue or mounting hardware. I have also provided the combined A+B parts to save you a step when printing on a dual extruder. (MinecraftOre_AB_v2.amf.xml) Enjoy! This is a Minecraft Ore block that is illuminated from the inside with a Neopixel RGB LED module. By changing the color, you can make it look like iron, redstone, diamond, emerald, lapis, or even gold ore. The block is 64mm on a side. Printed on a dual extruder using natural PLA for the veins and grey for the body with 100% infill.
