About this 3D model

This is a transparent PLA printed ruler. The scale hidden in the groove is not easily worn out. In order to get a smooth sloping surface, I used Bambu support filament for PLA. This is a gift for me to purchase the machine. I didn't used Bambu transparent PLA filament, I used SUNLU's. I just have it. I used 0.1mm layer height, 1 walls and 20mm/s speed. The transparency effect is good. The line width of the scale mark is 0.42mm, I used 0.4mm nozzle. Maybe I will test 0.2mm nozzle for transparent PLA.
