About this 3D model

I teach grade 5/6 and we talked about creating a retro themed Christmas ornament. The design is space invaders influenced with the shots coming down slowly destroying the shield over the letters. Took a number of tries to get it flexible but now works. My students will be building similar trees this week with their favorite 8 bit character on top for their parents. Thinking of creating the other space invaders characters for some variation. Had a lot of fun making and printing this! This object was made in Tinkercad. https://www.tinkercad.com/things/11RnyCEWpiX
