Model is created in Zbrush. Model is watertight.
I am providing source files from Zbrush and files in blender which are correct size. Fbx and obj variants are provided.
Also there are Stl files.
Model is 15cm long from nose to tail. But you can easily resize it in any 3d software that you are using.
I hope you like the model. If you need any help with the model feel free to contact me.
