I think I may end up having to go for a square piece for now. I pinched an old microwave plate that's the exact size I need. Unfortunately it's got those three annoying bits sticking out the bottom of it to attach to the microwave, and there's a slight dip in the center of the flat surface. Not sure if it'll be any good for heat transfer as there would be a ~1cm gap between the heat bed and the plate.
I'm looking at the possibility of using a slightly modified base for my printer, with a sprung bed. Basically I was planning on either getting an acrylic, or hardboard piece cut that will sit on top of the triangle shaped base, then have a raised surface from there, with some fans positioned under the bed to allow better cooling of the rumba board. Basically the end result will be that the base is fully enclosed, with cooling and the head bed and glass will sit on top of a circular insulated plate.
Theoretically it'll work...in practice I have no idea! :P
