I think that I can make one of those. I will have to do some research on materials though. The 5-sided (square ish ones) might be a bit easier but i would have to try it first.
The museum site was kind enough to give dimensions of the items in the collection which is a big help. I wonder if copper or steel would look OK? However copper is super expensive right now and steel is hard to work.
Does anyone have any thoughts on those metals?
