Potential incoming jerk comment:
On one hand, yeah that's cool, it's huge and it functions.
On the other hand, I think Tony Fisher is cooler because he builds and mods everything almost entirely by hand. It's not just
3D print and assemble.
Now he did 3D print 3 stalk pieces for the Core (so they're exact), but then he treated those 3 stalk pieces as 'masters' and made a mold so he could make exact copies by hand.
Which means his Megaminx is actually built by hand. Even the pieces were built by cutting out sheet plastic, gluing together, assembling, etc.
That's really a ton of work and something I admire tremendously.
The HUGE 3D printed Megaminx didn't even have the 3D print-lines sanded off the pieces. It's just printed and assembled.
So yeah there's a,
"wow, neat that's really big" factor to it, but it's not at all on the same level as Tony Fishers puzzle. I admire the craftsmanship and built by hand nature of Tonys puzzles.
