This is an alteration of my design of a 3D printed globe that utilized 300+ magnets to hold all the tiles, villages and numbers in place (see pictures). With polypanels this system can be extremely simplified: the panels don't need to be glued together.

To keep with the philosophy I've also designed the villages, tiles, numbers and streets in a way that they snap in place removing the need for any magnets.

All the designs are made with Tinkercad to prove the versatility of the program. The tiles snap to the inside of the altered polypanels and the panels are connected inside out, this ensures the printability of all the parts without support.

Because I've only got green filaments at the moment and there is not much time left I've printed a sample of 3 panels, 2 tiles, 3 numbers, 2 streets and a village to prove the printability and snappability. A picture of my previous (magnet) globe is also added to show the potential and final idea.

The top and bottom parts have to be mounted opposite of each other and a 10mm rod can be used to slide the globe on in order to be able to rotate the globe.

Adjustments to the rules:

Exchange harbors are replaced by exchange "numbers". The arrows point at the nodes/villages/cities which can use the exchange harbors. The surrounding tile defines the primary resource that can be exchanged. the 3:1 ratio can be placed inside the water as an island and you can exchange anything in this ratio.

The robber can not be placed on top of a token but should temporarily replace the token instead.

p.s. as mentioned above I'm short on filament at the moment, I'll be printing the complete globe in a couple of weeks but at the moment the few green parts combined with my previous design should suffice as a proof of concept :)
