I found this dragon prusaprinters.org/prints/31578-dragon by prusaprinters.org/social/70229-albaro_3d but it was in one single piece. I used meshmixer to slice it into pieces. I sliced it for printability with minimum supports and maximum preservation of details. This was specially tricky with the mouth so I had to cut the upper from the lower jar. It's the first time I have sliced an object for 3D printing, so it's not perfect.
I added connector pieces but since I could not figure out how to make perfect cubes in meshmixer, I created "+"-shaped connectors where possible. These are not meant for perfect connection but as a tool to help better glue the pieces together.
I am sure someone with more experience can do a better job then I. The photo shown is the glued-together printed full piece with rudimentary gap filling (using putty).
You will need supports from the build plate but likely no supports from the model (I did not use it).
The author remixed this model.
I sliced it up for FDM.
