Here's Luke Skywalker who has cause me so much headaches finishing up. At first I wanted to make Luke from Return of the Jedi, but then I figured that has already been done, so I decided to make a more unique alternate version. Being the idiot I am I decided I wanted this one to have switch-out heads variants, and a lightsaber with or without the light beam projected.
Both the heads and the body require some supports, as you can see below. I highly recommend printing these with supports as shown below in the animated GIFs, since I have had actual success when doing so.
I have tested the fittings of the keys at different scales. At 100% it works well, of course, but I realise he is very 100%, so you might want to scale him down a bit. At 75% the keys also fit very well, but if you print at 50% you might have to do a little bit of sanding!
Animated GIF:
There are two busts. The easiest is the one with no lightbeam extended.
Just remember if you print the lightbeam you need to put a proper brim on it, or it will probably get knocked over when printing.
There are three lengths of the lightsaber. The medium one seems to have the best length, but you can print the small one if you're having trouble printing a longer object.
Here's just a few pictures of me putting test printing and putting everything together:
