These are Sortimo T-Boxx compatible boxes for the dual-layer STB BES 31 G version. These are perfectly compatible with the stock Sortimo insert and boxes (see pictures). That said, they are designed to be more space efficient than the original version and have more internal space. They are available in 3-sizes and print without support. Send a message if different sizes are needed.
The author marked this model as their own original creation.
