Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5139969.

This is a cover for a tissue box so that items can be placed on top neatly without falling off giving you more space.

You can print multiple exchangeable tops, or customise to make your own. Looks nice if you print the two parts in different colours.

Might upload additional custom tops later.

Can be printed without supports. I have also included a cut version of the box to save on filament if supports are required, the two halves can be glued together.
