This is a coffee stencil with a Kitty. It fits coffee mugs up to 10cm (if printed at 100%)
For my own collection I created a few of these following the same size and build for better storage.
The author remixed this model.
The original was unprintable as the image seemed to be digitized and the Prusa slicer was even not connecting the pieces.
Furthermore I added a different stencil shape for bigger cups and a border around it so that either the cacao is restricted to the stencil and/or that the stencil is stable on the cup while using it.
