Beware of the fearsome Rathalos. This is Rathalos from the games series Monster Hunter. This model does have a tail that can be removed. I figured it would be great in d20 games, get yourself a extra carve lol. A while back I uploaded a Rathalos that needed some work. Well that work is now done. I have learned a few more skills and here is the results.
I started with a gamerip from Monster Hunter Tri, from there I ran through makeprintable.com to make a water tight mesh. Then I posed it in Blender, that probably took the most time. Next, I sliced it up in meshmixer to reduce supports and make it easier to print. I included a whole model in the downloads as well.

To print I recommend turning on "print thin walls" and "horizontal expansion" us a multiple of your nozzle for the horizontal expansion, like 0.4mm 0.8mm 1.2mm. This is to thicken the wing membrane. All of the models will need to be rotated, lay the flat side on the print bed. Cura's lay flat button works well for this. You'll still need supports with the cut parts, the amount of supports are drastically reduced. You will probably also need to scale the tail pin smaller than the rest of the parts. Dependa on how accurate your printer is. I scale the tail pin to 1300%, the base 200% and the rest 1500%. This makes it gargantuan size in DnD, Pathfinder, or 28mm scale. I printed with a Alunar m505, Dazzle Light white Pla, 0.12 layer height, 200c nozzle temp, 0.4 nozzle, speed of 50 mm. I hope ya'll like.
