Modified version of Albadr205's version as I was finding it difficult to print with overhangs.  Also rounded off the sharp corners at the top.

I've added some wedges under the overhangs, set it at a 45 degree angle and painted on some manual supports. Took me a lot of trial and error to get this printing nicely. The supports seem to come off pretty clean.

I recommend it is printed at 0.16mm layers or lower and a slower print speed.
