These heart decorations are made up of two separate intertwined chiral channels of the Laves Graph.
According to Wikipedia: “An object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superimposed onto it.”
Different but complimentary. Maybe you and your loved one are chiral?
The channels in the “small” file are approximately 2mm in diameter, which is as small as you’d want to go with a 0.8 mm nozzle. The example in the picture above is printed with a 0.8mm nozzle, and up close you can see a few imperfections. If you like this size, I suggest using a smaller nozzle. If you want to use a 0.8mm nozzle, I suggested scaling up a bit.
The channels in the “large” file are approximately 3mm in diameter which will print fine with a 0.8 mm nozzle.
If you have access to a multimaterial printer, printing the channels in different colours would look very cool.
