I guess you didn't read the title? That's the whole point, if i pick "tree" they don't support the overhang. If i pick normal they start floating in mid-air.

Try printing with a brim to stop it falling over. Make the brim quite wide. You will also need to activate supports to give something for the overhang to print on.
Since the hole does not go all the way through try printing with the rectangular end down.
It will be much easier to print with 0.2 or maybe 0.3 nozzle and a small layer height 0.12 perhaps.
Whenever I do something this small it takes me 3 or 4 tries to get the dimensions so it fits wherever it goes. If the hole goes over a rod I find the layer overhang binds so its best to clean the hole to size with a reamer or drill - just turn by hand as you're only cleaning off a few thou.
