This 3D Knot Puzzle is one of the things my grandfather used to make back in his woodworking days. I know it from the German crafts-shop “OpiTec”, who sold it as a DIY-Kit. (Also known as the “Devil's knot”)
Using their provided dimensions, i remade the individual pieces in Fusion360.
The 3MF-File is scaled to 50% (80mm long), and includes print settings for Prusa MINI with PLA.
The Fusion360 file is based on user parameters. Feel free to change them to your liking:
