Decorated Iso-Area Tetrahedron: CP
As per the series of models Oschene and Melisande have made, this is my attempt at a solution to the tetrahedron "problem".
Perhaps considered impure because of the external ridges that decorate it...
There's actually 2 ways of locking it... you can put the triangular flaps completely underneath the formation of the adjacent flap in clockwise fashion, which is extremely difficult to undo after curling in the last flap... or you can just tuck the tips of the flaps under the curved external ridges, for a more practical duo container.
I haven't figured out a way to fold this from landmarks... Suggestions are welcome.
One regret is that this model is extremely inefficient... Also note that the square twist in the center is supposed to be a cross section of the tetrahedron, but it's edge-length mathematically turns out to be about .7% too large and slightly misplaced... There would be ways to fix this problem I think, but it's probably not worth the hassle.
