I used the thingiverse model that this was based on and added pegs to assemble it after you print each piece separately. Just put it into your slicer and separate it into different objects. Don't worry about the spaces you see between the different parts, those were taken into account when designing the assembly pegs.
Note: I have yet to print this, so I don't actually know if it will work.
I know its not a great picture/screenshot but its what I got.
The author remixed this model.
