watch strap
This is a wristwatch strap I have designed when the original one for my watch broke.
This MUST be printed with a flexible filament like ninjaflex or something in the same flexible range.
You most probably HAVE to customize this, at a minimum the length. Sorry but I have not bothered with the customizer for this, you have to edit the file and run it in openscad manually. It takes quite a while to render.
