Neuroshima Hex board

Custom board for the game Neuroshima Hex (edition 3.0, other versions might need a different hex size).
I've always found the original board too large, and fiddly when it comes to removing a piece from the middle of the board.
This custom board has the minimum possible size, and has raised walls so that the tiles fit snugly once placed and cannot move. A placed tile can easily be moved or removed from the board by pressing one of the 3 marked corners, lifting the opposite side.
A filament swap is recommended after the layer height 3.2mm, so that the indicators are printed in a different color.

The file `test_fit.stl` is just a single hex, in case you want to check whether the tolerances are ok before printing the board. If it does not fit, the variable `base_hex_width` should be modified in the openscad code.

There is also a custom score tracker, since the original one is on the board itself. This one also requires a filament swap after the layer height 1mm.
