Great minds think alike! I think our machines probably are going to be pretty similar 
Sorry to hear about the progress. Keeping the house in order is very important. I’ll be moving into my own house this spring and I’m imagining I’ll be spending most of my free time getting it ready.
Yes, actually! 
Although only by chance, the footprint is very similar between the linkage and rings.
I modeled up the ring when I saw @bar’s template for it in the ring development thread:
I’m not sure if the design has changed that much, but it looks like the ring should work quite well. There’s a lot of clearance on the inside so the bearing carriages should be able to move around without hitting anything.
I have the kitchen for my new home to draw tonight, but if I have time I will try to get the parts nested as well. When I do, stl’s/dxf’s/svg’s for all! 
(I believe Fusion can output svg)
