This is a front lights holder for Topeak's Fixer 8 accessory.
It is printed as two parts, which can be glued together. Be sure to glue parts when they are uninstalled from Fixer 8, so both legs can be placed closer together (move inwards 1 mm), creating tension when the holder is installed on Fixer 8. Use glue that works best for your filament material.
