The "simple" turtle is just the silhouette of the turtle with the eyes and nose embossed. The "detailed" turtle has a shell and some other details added on to it.

Both turtles will need supports. I will see if I can design a support-free turtle soon.

Recommend scaling up unless you want a 3cm by 3cm turtle. The details are .1mm thick at 100% scale so I recommend printing at .1mm resolution if you don't scale it up. I would refrain from scaling down unless if you're printing on a resin printer.

Will upload photos and more information after printing.
