It's a cute yorkshire terrier puppy as a pen holder. It's a multipart file, so you can print each part separately without supports, the parts fits in the body holes but you need to glue it to secure, enjoy printing! :)

For the eyes you can use the "Filament change" option in your slicer to have the two colors (white - black). If you have a multifilament printer active the purgue tower, else you can add a cilinder to do this function in a regular printer. This model doesn't need supports.
