About this model

My son is a huge fan of dinosaurs and fell in love with the Flexi Rex by DrLex so I decided to do a series. I based all of them on the link dimensions he put in the picture at the bottom of his post. This is the first dinosaur in the series, I plan to make 5 total. I tried to keep this one like Flexi Rex, note the eye and mouth. My others become a bit more realistic and less cartoonish. I still really like flexi though. This was my first real attempt at creating anything flexible. It really helped me test the limits of things I can print and just how few supports you need sometimes. Thanks for the inspiration! Enjoy!
