Another reverse-engineered part: a small plastic cap for a Honda Civic MK8, designed to cover a bolt in the trunk. Since I couldn’t find the exact name or description of the part, ordering a replacement was tricky—so I decided to create one myself.
The top-left image shows a reference photo of the Honda Civic MK8. On the top-right, you’ll see a render of the custom-made cap. The bottom image shows the cap installed and fixed in place in the trunk.
