Printing those dinosaur hinges in place can be a challenge. I found the smaller versions to be more difficult than the larger ones simply due to the tolerances. You didn’t indicate whether the problem was breaking the hinges loose or if a coupling link curled up and caught the extruder so an X-Y stepper slipped and shifted the pattern. I had a couple cases where the extruder caught and shifted the pattern just a tiny bit (almost an unnoticeable millimeter) but enough that the hinges were rigid. I also had an adhesion instance where a piece broke loose from the print bed and slid around messing up the print.

On the plus side, you can use these STL files to tune your slicer and your printer. Take a look at the “Randomized String Art Ornaments” model description that I posted. I discussed some of my “Learning Pain” in tuning my slicer and printer to get those objects to print. My suspicion is that if you can print one of the ornaments, a dinosaur will be no problem. I’m curious to see if slicer and printer tuning can solve your “dinosaur” printing problem.
