• 0.5mm Line Width (for CURA)
• 0.2mm Layer Height
• 6 Top/Bottom Layers

• Heated bed – 60C temperature

Optimize Tool Paths

It's important to thoroughly check your slicers tool path. Most slices have a visual "layers" mode to see the individual layers and movement of the tool head. Step through the layers and inspect how the walls/perimeters will be printed. You should have a solid 3-wall count. If there's a noticable gap between the inner/outer walls, you may need to adjust your slice settings until it produces a 3 perimeters. In Simplify3D, the desired setting is under Advanced > Thin Wall Behavior > Allowed perimeter overlap: 50%. 

Line Widths

It's important to set the slice settings so that the walls are printed with 3 perimeters. This gives the part rigidity and provides a clean tool path. This does not relate to the "Outline/Perimeter Shells" that should be set to 2 (referred to Wall Line Count in CURA). The thickness of the walls ought to provide 3 solid perimeters. You'll have to adjust the Extrusion Width (referred to as Line Width in CURA) in order to produce 3 perimeters.

First Layer

Getting a good first layer is crucial for succesfully printing the parts. It's also important to have good bed adhesion to avoid warped corners. Depending on your 3D printer, you'll may or may not have a heated bed. You might use blue painters tape but I suggest using a printing surface such as a PrintInZ skin. This subtrate is great for non-heated bed and offers really great bed adhesion to minimize warping.
