Love the look of these unfortunately the jaw attachment broke 3 times! And maybe it's an issue using silk. Or there's some trick to attach that piece. I printed the TRex and the Spinosaurus (just the top jaw the second time) and unfortunately on all 3 prints, one of the little tabs broke when trying to attach the head. Thankfully I was still able to get the head to attach though I don't know how long it'll hold.
