Print out the Base, Top, and Center Column pieces as the color of the stone, then print the Diffuser in white or a translucent filament.
Wrap the center column in LED lights, then place it inside the base. Hot glue can be used to hold the center column in the base but is not required. Once the center column is in the base the diffuser can be fit into the top and placed on the assembled base.
Now you have a Minecraft ore block light.

I printed this at 0.2 mm resolution at 5-10% infill, and 100% infill for the diffuser.
All parts should be positioned correctly for optimal printing.
The author remixed this model.
Increased the size of the inner-block and Shell to fit the base that I designed.
