A full Catan board I made with custom pieces. I designed all of what you see in Blender except for the robber and card holder. The only thing not included to play the game is the box (found one on Amazon), cards (found on Etsy), number tokens (Etsy), rulebook, and build cards (I didn't include these). Links to these are below but you can also use the cards/tokens from the regular game.

The robber piece I remixed from https://www.thingiverse.com/thing:906562

The card holder can be found here: https://www.thingiverse.com/thing:2776071 I did not include it in my files as I did not make any adjustments to it.

"Pieces_box" is for the set of "full_pieces" (roads, cities, settlements) The "cup" is for rolling the "die" The "card_box" holds the cards for storage when not playing. The 6x hex pieces can each take 6x 3x6mm magnets glued underneath. I printed them flat. Link to magnets is below. Make sure to alternate polarity so they adhere together correctly. The "hex_holder" holds the tiles when not in use. "Largest_army" is the trophy for largest army. "longest_road_cart" and "longest_road_wheel" are fitted together to make the longest road trophy. "number_holder" holds the number tiles. The ports are all individual but can be batch printed together. The "robber" is the remixed robber piece.

Magnets: 19x6= 114 for tiles, 9 for ports, total 123 https://www.amazon.com/gp/product/B07873ZCY4/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 Cards: https://www.etsy.com/listing/1044494453/resource-and-development-cards-high?ga_order=most_relevant&ga_search_type=all&ga_view_type=gallery&ga_search_query=catan+cards&ref=sc_gallery-1-1&plkey=d114d4bd0478448fed91db96e91c138fc7d36200%3A1044494453&bes=1 Tokens: https://www.etsy.com/listing/1016716943/wood-replacement-number-tokens-with?ga_order=most_relevant&ga_search_type=all&ga_view_type=gallery&ga_search_query=catan+tokens&ref=sr_gallery-1-6&organic_search_click=1&bes=1 Box: https://www.amazon.com/gp/product/B088ML3WXB/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1
