This is a deer, which can be used as a wall decoration or in any other scene you like.
If you have a Creality 500 printer at hand, you can print it extremely large.
Under normal circumstances, you don't need to use a base to support the model, but whether it's necessary depends on the adhesion between the model and the print bed.
I also provided G-code files suitable for Creality printers, which came from Cura and S3D respectively. Interestingly, due to the algorithm differences in Cura, the slicing files generated for the same model in Cura took about 1.5 hours longer than those in S3D.
If you want to explore further, you can also download the files in SVG and PSD formats to take a closer look at the entire printing process and make more detailed adjustments and optimizations with Fusion 360.

Wish you a great time!
