Ball in a Cage Puzzle

An interlocking block puzzle from the 1940's. Try to disassemble the interlocked pieces and get the ball out of the cage!

The files are the individual blocks. Print 2 of fig 3, 5, 6, and 7, as well as 4 of fig 4. Then assemble the pieces and add your own ball printed or one you have lying around (it needs to be 17-18 mm in diameter)
