I designed a box insert for Cascadia with Landmarks. 

The first part holds all the starting tiles, the Landmarks scoring cards, the base Wildlife scoring cards, and both scoring sheets. Printed in PLA, no supports.

The second part holds all the tiles from the base game and expansion. I use it in-game as well to hold the tiles in use. There are 130 total tiles in total (85 base, 45 Landmarks), and the organizer can hold 138 total. Printed in PLA, no supports.

I also printed tjdesign's Pinecones and Stump as new Nature Tokens, Raymond DiDonato's Landmarks Tokens organizer, and Dajomas's Tiles tray for use in-game. It all fits in the box as shown
