This is an insert designed to fit the retail version of Earth from Inside-Up Games. It supports premium card sleeves—I use Arcane Tinmen AT-10423. I have also added some card tableau grids (printed in two pieces per player), all of which fit in the retail box with little to no lid lift.
NOTE: You will need a printer that can print at least 253mm x 193mm to print the tableau grid and grid holder pieces. You can print the other pieces on a slightly smaller bed but the grids are an integral part of this insert.
The boxes print best at 0.16 line height (0.4 nozzle) but 0.20 or thicker is fine for everything else. You really want to use 0.16 (or lower) for the boxes with lids as there are some small but steep overhangs that are supported much better by a slightly smaller line height. (Check your slice preview.) No supports are needed if you print at 0.16 or lower.
I printed these with 15% gyroid infill, but you can use 10% infill if you increase the number of top shell layers by one (or if you don't care about slight imperfections in the bottoms of the boxes). PLA/PLA+ works great for all of these.
The number of copies of each model to print is at the end of each file name. The tokens shared by all players have two storage boxes each to allow for easy access by all players. The score pad fits into a notch in one of the two trunk/canopy boxes. The first player and active player tokens have their own slots on the end of the card box that holds the non-Earth cards.
Finally, the lids for all the boxes are friction fit and can be stored on the bottom of their boxes so they don't get lost during play. The tolerances on these can be somewhat tight, but they came out beautifully on my Bambu X1C.
Model specific notes follow:
<code>2x4_card_grid_holder_x1.stl</code> - This keeps all the card grid pieces nicely organized in the box. Print 1 at 0.20 line height.
<code>2x4_card_grid_x10.stl</code> - The tableau grid pieces. Print two per player color (if you care) at 0.20 line height for a total of 10 pieces. I painted the solid bottom half black and printed the thin divider parts in player colors which gives them a nice accent, but this requires either an MMS or pausing printing at layer 5 or 6 to swap filament. These would be fine in pretty much any color and it really isn't necessary to use player colors.
<code>canopy_trunk_box_x2.stl</code> - Holds canopy and trunk pieces, along with the score pad. Print two.
<code>earth_cards_holder_x1.stl</code> - Holds all the Earth cards in a single box that is intended to be placed on the table to hold the cards during play. The angled lip on the bottom raises the box for easier access to the cards during play. The lip was designed to print w/o supports but at thicker line heights you might find print quality suffers on this bit. Print one.
<code>multi_card_holder_x1.stl</code> - Holds all the remaining cards, separated by their kind (Island, Climate, Ecosystem, Fauna, and the solo cards), along with the first player and active player tokens. The compartments have text embossed in the bottom to help identify which cards go where. Print one.
<code>players_tokens_box_x1.stl</code> - This just holds the 5 player tokens for each player. There is quite a bit of extra space in this box. Print one.
<code>soil_box_x2.stl</code> - Holds the 1/5/10 soil tokens. (I printed the tokens designed by Kandyhouse here: https://www.thingiverse.com/thing:5923585) Print two.
<code>sprout_box_x2.stl</code> - Holds the sprout tokens. Print two.
