I like it a lot to creating something movable that you can print pre-assembled, here is Turtle. It's a easy print and doesn't need support!

There is a small pillar under the neck that you have to break or cut off after printing, this might be a bit tricky, let me know please. 
I would also advise to use a brim to keep the different parts better in place while printing.

I just printed one in 90 minutes with these settings:

Print speed 50mm/s 
Bottom, outer wall and top 0.5mm 
Layer height 0.15mm 
Infill 25% with a speed of 75 mm/s

If you want a really nice print, just lower the layer height.
