This monstrous mimic box has a flexible tongue that's optional. It just needs to be glued in. The teeth are printed separately and glued in the place. All teeth are numbered, so there's no mixing them up. The box is connected together with a single piece of 1.75 filament. you just have to melt it on the ends to keep it in place. There is space for 3x2 mm magnets. Like most of my stuff, easy painting is kept in mind when designing. But unfortunately, I could not make the eyes separate in maintaining the goofy eyeball look that I wanted. That being said, I printed in a nice satin black and paint on the desired color and then go back and touch up the eyes easy enough. But for those that own a bamboo and an AMS, there are fully painted files for you set up to print five boxes at a time.
