If something isn't clear please ask in the comments.

Goal of the puzzle: fit all of the gear pieces onto the board.

-you may only insert 1 gear at a time.

-when you insert a gear the guide lines must be aligned with the rest of the board (not diagonally)

-you can't insert a piece if an adjacent piece blocks it.

-rotating the pieces is allowed as long as their guide lines will be aligned at the end of the rotation.

-the solution doesn't have to be able to rotate.

you need to print each file as many times as written next to the X in the file name.
