My print of Kirbs' model was not very kid-proof: one of the links broke after some rough handling. Hence I made all links more robust. This means this model can probably be printed even smaller than the original ones before the links become too weak. Of course you can also scale it up at will.
If you want to create your own flexible model, make sure to check the Hinge Design section below.
Printed with 3 perimeters for more strength. No supports needed.
This should move freely right after you take it off the build plate. If you print with hairspray on a glass bed, the Rex should spontaneously jump into a random pose all by itself when it pops off the plate after cooling down. If you need to use force to free the hinges, you still have some optimization work to do on your printing technique.
If you want to create your own flexible model, by all means copy the hinge design from this one, or at least use the below image as a guideline. I see way too many ‘flexi’ models that still use the weak hinge design from the original model, or other shapes that have way too little material in the most crucial locations, often the end of the shackle or ‘ring’ is too thin. Make sure to provide as much material around the axle hole as possible, instead of cutting away as much as possible, as some designers tend to do. You won't gain any flexibility by providing more clearance than needed, the model will only become weaker.
