I've remade the triceratops head 141% larger than before. The neck joint now fits perfectly inside and the head is a better size overall. Next step will be to rough out the body parts at a suitable size and start joining everything together.
I made a quick stop-motion video showing how the neck joint moves. I've uploaded the video to Instagram & Facebook but thought it was probably too short for YouTube so I've tried embeding the actual video file here. You may remember that I tried it embed a video a couple of years back with mixed results. I'm hoping that browsers have got better at complying with HTML standards over the years.
Please can you let me know if you can see the video below. If you can't see the embedded video you can view the original Instagram video by clicking on this link.
