Here is a glowing Jack-o-Lantern, ready to light up any Halloween decor. This pumpkin is powered by a single tea light. The colored filter is 3D printed and can be printed in any color. Placing the filter inside the pumpkin is optional if a more traditional candle look is what you want. When putting the filter into the pumpkin I recommend using a tool like a paint brush handle to help maneuver the filter into place. There is a small lip inside the pumpkin that will hold the filter in place and at the right angle to create that eerie glow.
