I started drafting an acrylic armature, with the end goal of having a side and bottom mount. I will make the .ai files available once I dial in the measurements, so if you choose to do the same kind of thing you can have the parts laser cut. Here's where I am at the moment:
There will also be a neck collar, and the equatorial transition ring from top of body to bottom. Mars had a great idea to cut it in the shape of the Imperial cog, which I love! No one but the builder will know it's there. Fun!
Also going to lasercut the leg discs with precut holes for the hardware (so no sweating the drill press!). Maybe some leg sections too, depending on if it makes sense. I'd love to offer a super-sturdy solution.
