My Floatwheel ADV Drop-Top Fender Bases keep cracking and I wanted a way to print replacements without a ton of supports so I split the OEM model and made some alignment pins to help me glue it together. The top half still needs a small amount of supports but a fraction of what it needs when not split. I also extended the bottom half so it better fills the gap between the bumper and fender.

• Walls loops: 5
• Bottom shell layers: 5
