Playing with fusion360 I made this. Can be used ad home decor , or if you shrink it as a gift decoration, or I don't know ... Waiting for suggestions.

You can try with raft , with support or without ( it's depend a lot if you reduce the model or not ). In all the cases the lower face will not be as good as the upper .
I think the only things to do if you want a perfect object is to split the model in the middle and use glue.
