This is a (dual) spool drawer, customized for the Häfner SD 200 K used by e.g. Dasfilament and FormFutura. A labelling field has been added, but I did not test if the parameters still work. Just compiled that specific STL and printed it unaltered as well as mirrored. Starting point was the ColorFabb Spool Drawer by Eriobis (https://www.thingiverse.com/thing:2056090), which is a parametrization of Spool Drawers by SpectreGadget (https://www.thingiverse.com/thing:2011130), which was inspired by Spool drawer organizer by Tanatof (https://www.thingiverse.com/thing:2009550).
