After watching Chris Ramsey Attempt at Stephan Baumegger's Excalibur puzzle on YouTube ( https://www.youtube.com/watch?v=__OCUHE2Fwg ) I wanted to play with one myself but wasn't gonna spend 130 dollars on it so instead I found the solution guide and remade all the pieces its printable and fits together however I have not finished piecing it together yet because it is a level 10 puzzle. Good luck solving it yourself.

this video does have the solution to putting it together and another video on the same channel on how to solve it I have put it together with this video

A few pieces need supports you will probably have to rotate them around for the best orientation i printed the sword upright with supports and the center base of the sword with supports as well as one of the pieces.
The sword glues into the sword base and the top of the cube needs to be glued onto the cube base
