These files are designed for the most part for laser cutting. But if you are not confused by the small size, you can also print them on a 3D printer.
To increase the size, you can cut these models into pieces, print them separately and then connect them with glue.
STL files are ready for printing on a 3D printer with a maximum print area size of 210×200. If your table size is larger, you can easily scale it to fit your size. To make a large-sized version of metal, wood or plastic, as in the picture, you will need the help of a laser cutter. To do this, I added dfx and svg files.
Wall mounting can be done using double-sided tape.
To achieve the wow effect, you can place an LED strip on the back of the decor.
