Need suggestions on best orientation for this object

Printing a christmas ornament in clear at 25 microns. Should take about 16 hours. AND, I will need to eventually do 12 of them (1 for each grandchild), each with their names on them. Needless to say, I don't have a lot of time for experimentation. After a successful first print, I hope to print 3 or 4 at a time.

So, I am asking for input about the optimal orientation for this. I prefer to have few or no interior supports, but the final closed portion at top may require it. Your opinions welcomed. Obviously, a failed print 13 or so hours into the job would be VERY disappointing.

Ideally, I will start a run tomorrow (12/12) evening, so quick responses are greatly appreciated.

Thanks in advance for your help.
