I made this for a younger family member of mine who loves dinosaurs and loves to color! The crayons don't quite fit right on the tail, but it works. 

Print it flat on it's side, and I would recommend supports. If you have good support settings for large open areas, you could likely print it oriented the same way you'd set it on a desk. I did it on it's side, and pulled out the supports with needle nose pliers. 

I printed at 100% density for kid-proof durability, but that was likely overkill. 

I recommend Polymaker Polylite PLA Pro in white, because it makes for a very drawable surface, and lets the model be colored on as well!
