Let a hippo hold your clothes :)
 

Printing Recommendations: 0.2 mm layer hight, no additional supports needed, for a robust print choose 20+ % infill and 3 perimeters.

Remark: The base model of this design was created by HeavyMetalGuy.

Tipp 1: The model comes with a hole to wall-mount it with a nail. 
If the surface is suitable (like a door), the hook can also be attached with power-strips.

Remix Documentation:

+ Remixed both eyes to have open and equally open lids.
(base-Model: one is closed and one is slashed)

+ Removed some symmetrys which made the base model look unnatural

+Redesigned opening for hangig to enable both: fastening with double-sided tape and hanging on a nail. 
(base-model hasn't had enough flat area for proper fastening with tape)
