ColorFabb Corkfill Filament
If you like cork boards and wine corks, you'll love Colorfabb's new Corkfill! Corkfill is an exciting filament which looks, feels, and behaves just like cork material. You can use this filament to make light weight wood objects or traditional cork items such as dart boards and custom wine corks. Corkfill is a combination of PLA and Cork wood fibers. Because it's PLA based, you can print this filament on any printer than can handle PLA filament.
