Forest Shuffle Insert

Summary
This is an insert for the game Forest Shuffle (English edition, USA distribution). Box size is 220mm x 160mm.

The Design:
* Maximize the use of the space available in the box.
* Removable card holders that can be used for draw and discard decks.
* Support Sleeved cards, up to 59mm x 90mm (unsleeved cards are 56mm x 87mm).
* I scaled the playing card holder from https://www.thingiverse.com/thing:5430586 to fit the needed box & card dimensions.
* I designed the spacer to keep the card holders in place while providing a slot for the playing board.

Final product:
* Zero lid lift. 5mm for Rules and Score Sheets
* Five (5) identical Card Holders. Leaves enough space for Alpine and Woodland Edge expansions.
* Two (2) identical Board Spacers to keep playing board and Card Holders in place.

Printing
* Print 5 of the Card Holders
* Print 2 of the Board Spacers. Infill can be low (e.g., 10%)
