SunShade Visor – miếng che nắng cho kính

This visor is very light, prints in one piece, and snap-fits to the arms of the glasses.

Worn on the glasses protects your lenses from the direct sun rays, giving you clear vision of whatever is happening on the beach (or you can wear a hat, of course, if it shades your glasses) 

This model is intended for 1mm thick glasses arms, let me know if other thickness is necessary.

As for the width between the glasses arms - it was designed for 140mm width. If your glasses width is different, especially when worn, measure it as x, and then use formula (x/140)*100% to calculate scaling factor for your slicer. It should be ok to scale width only.
