Complete Shoulder Joint for Skelly - 12' Home Depot Skeleton
This was put together hastily to help out a friend and I thought there may be others looking for these parts. I'm sorry I haven't had more time to clean up this project.
The parts 'inside' and 'outside' are the parts of the joint. I embedded a 5mm brass nut in the ones I made. There is a hole on the side for that.
The 'ring' can be put inside the 'bone' to beef up the connection. It's a little tricky to get it in there. I used the original screws and screwed the ring and the 'outside' part together separately before trying to put it all together.
You should be able to print from the STL files. I included the OpenSCAD if you're interested.
