I found this model on Maker World by mizioman and decided to make some for my Brother-In-Law for Christmas; he's a big Catan fans like me and I thought they would enjoy it. I didn't realize the first layer and top layers on his files were separate objects, so my originals looked a little rough :( and they didn't make it to Christmas because I was leaving the next day. Now that I'm home again, I decided to tinker with it a little.
I finally got those top and first layers centered and combined and it printed perfectly, but after I printed it I realized you couldn't store the pieces inside the boxes, they were just organizers for while you play the game. I thought that could be improved a little by allowing storage also. So I stretched the top a little, and quickly realized that the pieces would bounce around and not stay in place. (You can see my many failures in the pictures lol) So I continued to adapt the top by putting in a stretched, and flipped portion of the bottom to lock the pieces in on the top as well. Now it functions much better and allows for storage and transport without your pieces moving.
But I still wasn't done… I didn't like how the Cities set low and locked in, but the houses were shallow. I dropped the houses' slots a little and made them tighter. This is the first version, and I should have considered that these little wooden houses wouldn't be as consistent a measurement as they should be, so it was a little tight and didn't fit right. For v3, I just took the holes he already had, and made them deeper to 5mm. I had to print it in yellow because I ran out of red filament, sorry it looks odd in the pictures.
