Prints in under 4h with a 0.6mm nozzle, which I recommend for the look. No support needed, but brim is highly recommended.

Intended height for the green branches is 18cm or ~7", but 50% size seems to pass as a nice decoration item as well.

I don't recommend super glue 'cause it is turning white and vaporizing on your prints. Getting ugly really fast. Use hot glue oder plastic miniature model glue - this connection is cosmetic only.

If you wanna print the trunk with a 0.6mm nozzle, you can set the circumference layer number to 1 and save some filament. But only print one trunk at a time with this setting as the stability is dependent on a nozzle staying on the same circumference.
