Evil Puzzle - Aussie Edition !

Remixed from: https://www.thingiverse.com/thing:4039896

Added a bit of Aussie flavour to the original one I remodelled recently :) with an easy "print in place" hinge, now any printer can print this design if your slice height is 0.1mm - 0.2mm

Puzzle was difficult to open with the strong magnets, so I added a thumb groove to assist.

Both Difficult and Evil puzzles are solvable.

Hint:- the 4 pieces only have to fit into the designated recess all at once.....they do not have to fill all the gaps !
