Summary

Why does cheese sweat in the refrigerator? In any case, cheese becomes less tasty looking when all sweaty and soggy.
Most cheese boxes come with an inlay so the sweat does not touch the cheese.

Mine did not.

Luckily I have a 3d printer ;)

Designed in Tinkercad, simple design, but as of yet very effective.

For slicing I strongly suggest not to use Slic3r as it will create a print job that has more moves than prints where the moves are so many that the very little oozing my printer has builds up to a very visible and print-hindering line. See photo where I very crudely indicated what was actually printed and the moves are cleary visible.
When slicing with Cura, the print paths are all close together will nearly no unnessesary moves.

Edit: Just a friendly reminder; Neither PLA nor PETG is dishwasher safe :P (Ask me how I know ;). )
