Lion head pendant 3D print model

Well formed, loved its detalization. Have printed via 40cm tall, removed ring, and changed some proportions. It is now ready for bronze casting. 1. https://i.imgur.com/UdBs0eg.jpeg 2. https://i.imgur.com/6Z307RW.jpeg

the eyes of the lion in the image is big and when i open the stl file it is not that big enough..it looks very small in compare to the face size..when i use it in my cnc machine for engraving on carbon steel,the output has less details of eyes , so please make the eyes little big so that it looks proper in compare to face size..othwerwise other details and depth is good...

Nice model . but i am unble to increase the thickness after scaleing.
