Mini Reactor Pixel Art

Create a 32x32 pixel art item of a small reactor for Minecraft. The reactor should have a simple cubic shape with a dark gray metal casing. In the center, place a glowing blue core that emits light. The edges of the cube should have metallic reinforcement, and the core should stand out with a bright blue or cyan color. Keep the design minimalistic with clean lines and subtle shading, making sure it fits the pixelated style of Minecraft. No additional wires or complex details,
