Casio F91-W case

I designed this case for my Casio F91-W with a broken wristband. The purpose for me is to have it attached to my wetsuit when surfing and put it behind the chest zip and be able to pull it out by the string to look at it and then poke it back in (wristwatches are inconvenient with gloves and 6mm neopren in cold waters...). Or just wear it around your neck :)

NOTE The model must be printed with flexible filament to be able to squeeze the watch into the case. The model on the pictures is printed with Recreus Filaflex 82A TPU and it is a very snug fit. Softer filament would also work, but harder filament will probably not work!
