The Kilominix corner actually totally works, but the internal edges need to be drilled out.
I could do it, but I just don't feel like drilling that many holes.
What we're (Highly) considering doing through the Cubicle Labs line is allowing full custom orders. If someone wants a certain puzzle magnetized, tensioned, and stickered, we can negotiate price and do it for them.
I've spent the past month playing with magnets, so I'm getting pretty good at estimating what magnets to use, where to place them, and how to place them, and I want to offer more options to people. We can even have selective magnetic strengths and tactility. (The radius affects how many degrees the puzzle has feedback)
This also opens up possibilities such as FangYuan, Gans Air, etc etc.
Even stupid silly things like 7x7, 1x1, and non-cubics.
This means that Kilominix and Z-Man Galaxy Megaminix are totally on the table. (But please don't order too many, it takes SO LONG OH MY GOD)
Optimistically speaking, this could be offered within a few weeks even.
