964 DecklidThe Porsche 911 (964) rear decklid (engine cover) is an iconic body piece famous for introducing Porsche's first automatically deploying, motorized rear spoiler that lifts at 50 mph (80 km/h) to supply downforce and cooling

This was modelled for roughly 1/8 scale.It is not acurate to the real one, it is for display modelpurposes and It does not come with a lifting mechanism.You will have to fabircate one yourself.I printed it on a resin printer and not sure how FDM printing will handle the detail.I used standard settings:Layer Thickness: 0.05 mm (50 μm) is the industry standard for balanced detail and speed.Normal Exposure Time: 2.5s to 3.0s for monochrome screens; 6.0s to 8.0s for older RGB screens.Bottom (Burn-in) Exposure: 20s to 30s for the first 4 to 6 layers.Lift Distance: 6 mm to 8 mm. (Combined with a slow lift speed of 1–3 mm/s to smoothly peel the resin off the film).
