About this 3D model

I made this Advent wreath for the Tinkercad Christmas Challenge, when I read the design letter I suddenly came up with this idea when I thought of the big Christmas tree in New York at the Rokefeller center. As a "special design" I have designed the windows of the skyscrapers so that you can read the lettering XMAS on the buildings. This object was made in Tinkercad. https://www.tinkercad.com/things/2cF0MEh7lXE
