I have made a new version of the catan box smaller and optimising the space to the maximum and reducing the material used.
The STL lid is multipart so it can be printed both multicolour and separately for single-colour printers. In this case you will need and excellent fitting tolerances.
To assembly just need x6 M3 30mm
I recomend use at least negative tolerance -0,1mm in both cases.
The author remixed this model.
Used the parametric box to fit all catan pieces.
