The recommended print settings are:

• 0.2 mm layer height
• 3 perimeters (important, to make the links strong)
• 15% infill
• Solid infill threshold 8mm²

Expect about 2 to 2.5 hours print time for a good quality print.

Don't use a high infill value, this could cause it to become unbalanced. For improved stability, you could increase infill on the piece with the feet below it, and reduce infill of the head, but this should no longer be necessary if you print the current model with the above recommendations.

I actully made the model by accident way to big but you can scale it down in your slicer!
