In CURA review basic and advanced settings see... Check advanced settings for 1.2 nozzle, update profile if necessary

Steps per mm at 100

Layer check/ missing/ change thickness to 1.0 top, check'expert config' settinga no check on spiral contour bottom and top if already set to 1 in Basic and missing

Filament size using 2.85

Check machine settings bed size (does not update with profile update)

save /export Gcode to SD card

note: .stl is the geometry of object, the Gcode depends on the above settings for the printer to read and print

2 Using Inkscape to Generate Gcode

from Image Started with .png, save as .svg, at top bar path/ trace bitmap under multiple scans: creates a group, select colors, smooth, and stack scans was set to 8, could likely reduce to 2, select ok then move one off.

There will be multiple additional copies to delete

export gcode

this is the link to check the Gcode before plotting as above

And here are the files including the un-plotted Gcode file for the OSE sticker (no added lines to 90 for alignment)
