About this 3D model

These two identical pieces, if placed together in the correct orientation, will create a four sided pyramid. Do not underestimate this puzzle's simplistic look. Even though there are only two pieces, this puzzle is suprisingly difficult to solve. Of the roughly 30 friends I have shown, only three have been able to solve it. So print this puzzle out and attempt to raise the 10% success rate! For the solution, search for 'two piece tetrahedron solution' on Google. Please do not sell this design publicly. If you liked this then perhaps you'll like my other designs and puzzles. A like would be greatly appreciated. Thanks!
