If you use the attached inscription of the A.S.P. Button Box is no longer satisfied, there is now this solution. Note that this is the version without CB radio connection. If you have one, please create a recess with Fusion360.
I have enclosed them both without a label and with. Without labeling, it is sufficient to apply with a thin white edding (e.g. 780) (see picture) If you want it to be more professional, it means a little more work. I have included the Fusion360 file. There you can change the labels as you want them. The depth of the writing should be about 0.6mm, with a total thickness of the aperture of 1mm. When slicing, you should pay attention to the layer from which it overprints the font. Because from this layer you should pause the print and change to a different filament. White filament works best for this! Because of the small font you should print slowly and fine.
