This is a 3D printable replacement cover for Raymarine ST60 boat instruments. It should be printed using UV resistant material.
You could add your boat name to the cover. I've had good results with recessed lettering with a depth of about 0.3 mm.
I've uploaded a new, somwhat nicer, design with rounded edges.
This is a work in progress. Please leave a comment if you've found this design useful (or not).
