This is a chin spoiler for the WPL D12. It's a reinforced version based on previous free data, with increased thickness at the mounting points. Furthermore, the spoiler shape remains the same, but it's extended 3mm forward, and the mounting plate width is increased by 10mm to reinforce the area around the holes. The product is made using a layered 3D printer. The material is PLA+, and the layer thickness is 0.2mm. Packaging will be "bubble wrap + envelope". Thank you.
