This is a simple and fast to print seperation puzzle where you need to seperate the two pieces to solve the puzzle. It took me only 20mins in total to print it and you can have a lot of fun with it.
But the two pieces are printed seperately, so you need to put them together first, which is a puzzle in itself (I personally found it harder to put them together then to seperate them)
But keep in mind: do NOT use any force at all. The correct solution does not require and force and all the pieces should be easily rotatable to solve it proper.
In the attachements, you can find the printable STL file. In addition to that, i added a ZIP file containing the PNG sketch I made and the SVG file which I did generate from it. The SVG file can be imported into Blender or any other 3D program do manipulate it on your own.
Hopefully you will have fun with it. Let me know in the comments :)
