Just a simple shadow box display of Reptile (or all the ninjas) from Mortal Kombat using the MK3/UMK3 style pre-battle loading screen fighting pose.  You can also change the green color to:

Blue for Sub-Zero

Yellow for Scorpion

Red for Ermac

Grey for Smoke

Purple for Rain

Albeit, Scorpion and Smoke have slightly different poses from UMK3. I don't think black for Noob Saibot would work very well though, lol.  

Some of the holes shown in my printed design were fixed for the uploaded .3mf file, so will look better than what I have pictured. You can turn the plates inside around if you have a textured plate and prefer that look, or want to print two and have them facing off against each other!

Enjoy!
