I just uploaded the clamp model I used in the recent render with Lara. It's just a Daz import so nothing special, but I did clean up the rigging so it is easier to pose. Still just a simple 'bone' chain, but it works fairly nicely.
I'll probably improve/clean up the rig further next time I use it but hopefully it is useful.
You can find it in the 'Models' folder if you have access.
