This is a mobius strip of Level 1 or Super Mario Bros. The whole level is wrapped around itself in a single surface, and poor Mario begins and ends at the same spot every time :(

All the elements from the level are there: every mushroom, turtle, cloud and star. They are all carved out of the surface at different heights, which looks fantastic when you have a light coming from the side, and each block casts a shadow.

It's a great piece to have on your desk, or to hang from a string to let it spin around.

It arrived in WSF, and it works for real :-)
Gear system based on hypotrochoid shapes.
It is printed as a 9 piece puzzle, a VERY frustrating one at that ;-)

Depending on the print batch, it might need some minor sanding to make it run properly.

Steel available on request, still untested by me.
I think steel will work but probably needs some more sanding to make it fit.
With the new pricing scheme, the steel version is no longer available.
If you want one in steel, please send me a message and we will find a way.
