A replacement strap for swim goggles. Print with either flexible filament or if you have a resin printer with flex resin (better). I printed them with a Prusa mini in Flashforge Flex Filament and on a Prusa SL1S in Prusa Blue Flexible and Resione F69, both at 0.05mm layer height. Printed without supports and directly on the build plate (disable the use of a pad). The Resione F69 is more flexible and thus easier to mount and adjust, so I recommend it.
Parametric Fusion360 model provided for needed adjustment.
