Silhouette Faces Frame - Wall Art

A friend asked me to design a wall art piece for him to give to his beloved one. He gave me a sketch drawing and asked me to make it big to hang on the bedroom. This is the end result. Both of them liked it very much.

The complete frame has 700x300 mm. I separated all the parts with a size in mind to fit most printers. I've included a PrusaSlicer project 3mf file with all the parts needed to print.

The parts are fixed with super glue and the help of a straightforward clipping system. I use this glue:

If you want to completely remove the lines of the glueing zones from the parts you can use wood filler, sand it and paint over the assembly.
