A long time ago I made two 3x3x5 cubes. They took ages to make (a lot longer than I originally planned), so I'll be trading them rather than selling them. It weights 270g. Here's some shots...

Very mixed.

I do get a lot of emails requesting these even though they are extended puzzles. Eventually I will make these again although my main interest is casting Fisher Cubes, octahedrons, Jewels and rhomic dodecahedrons right now. If you want express interest in getting one made, you can email me privately or discuss it in the forum. I'll put you on a notify list in case I make a batch.
