Standard PLA+ settings. 

I printed with 0.3mm first layer and 0.2mm layers after, 5 perimeters, 6 (Top) and 5 (Bottom) horizontal layers, extra perimeters if needed turned on, random seam position with fill gaps checked on, 60% gyroid infill, 30% infill/perimeter overlap, and 2C over typical print temperature (for me that was 230C for PLA+ when typically I print at 228C for my printer). No supports needed.
