I printed the Model at 100% scale and 0.2 mm Layer hight. But for smaller Prints i would recommend printing at 0.12 mm Layer hight if you go under 40%.

Print Settings:

Nozzle: .4mm

Printing Speed: 50mm/s

Layer hight: 0.2mm

Infill: 10%

Supports: Place Supports as shown in the Picture. With Cura slicer i would adjust the angle until it places them right.

Printer: Ender 3 v2
