Biển báo trống Parametric

This is a parametric sign you can add your own text in your slicer of choice.

Instructions to add text:
Bambu/Orca: https://wiki.bambulab.com/en/software/bambu-studio/3d-text

Prusa Slicer: https://help.prusa3d.com/article/text-tool_399460

You can also change the size and dimensions as needed in Fusion360.

If you would like a different pre-made size post a comment and I will add the STL.
