All, this is not a remix of another's but was purely inspired from an online video short. Please go to https://www.printables.com/model/590620-brain-teaser-54-pcs-puzzle first before downloading this model. Her posting came before mine, please support her model first by like and download.

UPDATE added Fusion360 archive.

You will need to print 54 pieces of the puzzle piece and just one of the holder. Happy printing and solving :)
