I created this 3D cube as an art reference to learn persepective. It can be printed in about 45 min and requires no support as it is printed in 2 pieces.
The part has been design in freecad and the file is included to be modified at your convenience.

Designed in FreeCad, i created this piece with the help of a boolean operation between the roof and the holder parts. Otherwise I used basic extrusion and cavity.
