A scale model of my favourite ship from Elite Dangerous, the Cobra Mk III.
In White Strong & Flexible Plastic its 1:250 scale, but even at that scale its still 6 inches in width, at full size this thing is a massive 130ft wide!
The plastic version comes in two parts with a hollow interior so you can insert LED lights to illuminate the vents and thrusters. The Stainless Steel version is a single solid piece.
