Summary

Try and assemble the 3 identical pieces to make up a triangle...
This might take you (or your friends, or kids) only 30s, or you might need to think about this for a while, until you figure it out.
Please don't give the answer in the comments, that would spoil the fun ;-)

Post-Printing

The pieces fit tightly together, so they should be lubricated to reduce the friction.
I used machine oil, but dried soap should work just as well and be better suited for kids.
