Catan Hex Frame - Non-magnetic Interlocking

I don't like when the Catan hex frames slide around and the roads don't stay where you put them.  I also didn't like any of the magnetic frames because I didn't want to have to go find or supply dozens of tiny magnets, and all of the other frames were either larger than I wanted, or were an entire scene rendered in plastic.

So I decided to just go design my own.  These take less than 10mins to print on a Prusa Core one and only use about 3g of filament each.  The 3.1" hex tiles press in nicely to the frame and stay put, but are still able to be popped out if needed.  The roads are positively located in a recess formed between two pieces.  The settlements and cities aren't postively located, but tend to stay contained between roads when inserted.
