Here is my insert for the board game ‘Fun Facts’.
It perfectly fits in the original box, but therefore it's more massive then my other inserts.

The insert has compartments for the 8 arrows, the cards and the markers as well as a space for the first-player-star.

The way I printed it (no shell layers in the lower part, but at the top), it needs 240g of filament.
It measures 152x222x47.5mm (approx. 6x8.7x1.9 inches).
For smaller printers I added the 3mf-file with the cuted version.

I also worked on a filament-saving version (about 120g), but not finished it, since I focused on this. If you're interested in this, let me know.
