About this 3D model
Let me start this off by agreeing with you - yes, this is a weird idea! But I have an explanation - read all the details on my blog: https://edditiveblog.wordpress.com/2021/12/12/xmas-brain-decoration/ I don't think much more needs to be said - it's a brain decoration for your Christmas tree (or anywhere else) that says "Merry Xmas." Just drill a small hole in the top and you can thread a piece of string through for hanging.
