This is a small anal plug with the face of a cute electric animal carved on it. :)
This make a perfect kinky gift for those who like it.
With his hat on, no one can say it's an actual anal plug, make it easy to store on sight of all, making a nice surprise for those who take it ! ;)
This is not designed to be actually used as an anal plug, the size and shape are good but the carving used for the face could be irritating and also not hygienic at all.
For the plug : For the joke, any plastic can be used, yellow preferred, and after you can use marker or paint to paint the eyes and mouth in black, and cheeks on red. ;)
Better use high def settings to have a proper render of the face.
For the hat, anything will do the job.
If you actually want to use it, use an adapted plastic, rubbers plastics can be nice.
Use high definitions settings and try to broke it with your hands before use it, to be sure it's quite solid.
Also, always use condom with 3D printed toys it's safer to prevent any potential broke and it's much more hygienic ! :)
