This tissue box cover fits the Kirkland 8.2in x 8.4in 84-sheet tissues. Even though the tissue box claims to be 8.2" x 8.4", it's going to fit into this cover snugly whichever direction. No AMS required.

It's recommended that the lid as well as the body of the cover be printed with fuzzy skin. Make sure the lid uses the “contour and hole” option for fuzzy skin. With fuzzy skin turned on for the lid and the body, there is no need for any dedicated mechanical locks, even though when the two pieces slide against each other they make a bit of a nasty sound.

The strawberry body, stem, and the cream can be glued together and be placed wherever desired. That's my excuse for haven't figured out a way of reliably model positioning features in Blender just yet. Sorry :) 

The lid after slicing also has a weird piece of artifact on the interior that I don't quite understand how it's there. However, no one is going to see this side and the artifact doesn't affect fit, form or function.

The ring of piped cream also has some artifacts from the Blender modeling process that I cannot find a way to clean up just yet, resulting in supports being printed on the bottom face of the model that are difficult to mitigate. However, since the bottom edge of the cream is gonna lay against the lid, again, doesn't affect fit, form, or function
 

The idea for the model came after I finished the Blender donut tutorial and I was contemplating on how to model something useful. The other day I saw the ugly, beat-up tissue box on the counter, and thought “ah-ha”!
