Your first one and the one Jo has is what I have sitting in my tooling cupboard.
If you need the third angle, then a little Wixie digital gauge could be used in the beginning to set the part up in the vice jaws.
The more axis you start to add, the more throat on your milling machine you lose.
Even on my largish mill and a 3" jaw version of your first selection, I am starting to get tight on throat depth if the part sticks up any more than a couple of inches above the vice jaws (that is with an ER32 collet chuck, OK if I use spindle collets).
