The F56's sun visors are oddly shaped. They're thinner closer to the door and thicker closer to the centre of the interior. In addition, it's hard to use the many designs already out there because the vanity mirrors get in the way. While other designs don't fit the thicker interior side properly and bend out of shape, this design takes the odd proportions of the sun visor into account and will not bend over time.

MATERIALS: ABS is the best choice for this clip. A car's interior, depending on where you live, can reach temps up to the high 60C range, and ABS is both durable and temperature resistant. PETG is the minimum recommended quality plastic for this clip.
