I remodeled the design by MakeALot to have a high quality STL for my own use.I use Simplify3D which easily allows me to change print settings throughout the build. This part is split into 2 parts; the base, and the knot. I originally found the model through a Simplify3D tutorial which discuss's this process. Different Settings for Different Regions of a Model Base 0.3mm Layer Height 2 Shells 30% Infill Knot 0.15mm Layer height 2 Shells 0% Infill
