You mean petaminx?
As for both of the puzzles it would be quit impossible.
As Lee Tutt said on the DCD: It was hard to get all the pieces perfect, only 1 void megaminx was good. But still could be improved.
So for a teraminx there just would be to many pieces to perfect.

Anyway I have made two and am still not completely happy with them. The first is stickered and the second is tiled. The first is a little tight and the second a little loose. The spider can not be adjusted because there is no spider! This means the pieces have to be very accurate. Assembly is tricky also.
i dont kniow how to make a megaminx:(
