This thread from /po/ caught my interest, so I started on the Sol Emeralds, and I'm in need of a test builder.
Evidently I wasn't the only one unsure of the other dimensions of the emeralds (I could only find sprites that provided a front view), so I made three different versions. One is a flat, almost LoZ Rupee-like shape, one is more like a rectangular prism, and the other mocks an emerald cut.
The whole kit (a .rar), with .pdos and .pdfs (with and without lines) for each build is available for download here:
Probably going to work on my own version of the regular chaos emeralds next.
