I know it comes a little bit late, but better later than never. The package contains four model, three faces of different dimensions, for a 13x13x13 cm cube, 15cm and 17 cm. the faces can be connected to each other with bits of 1.75mm filament. If after printing the first face, the hole is too small, try scaling the model a little bit to be able to fit the filament. with 0.2 layer height it should fit snuggly. The effect from the photos was obtained by removing top and bottom layers in the slicer and using the infill pattern to give the nice look. The fourth model is a full cube that is a little bit of a torture test for the printer, but I think that with supports it can be printed successfully. It was a little bit of a test, I prefer to print the faces individually and connect them afterwards. Thanks for downloading mu model and happy printing :)
