1.75mm "DAS FILAMENT" Filament Clip

This filament clip is inspired by the "Colorfabb and Filamentum" clip from [this](https://www.thingiverse.com/thing:42528) thing. After trying several different designs I like this type of clip the best because it has a low profile, uses little filament and is fast to print. Since there doesn't seem to be such a clip for [DAS FILAMENT](https://www.dasfilament.de/) spools I designed one myself from scratch. I know that the "Colorfabb and Filamentum" clip *can* be used for DAS FILAMENT spools but
