To replace the glass on a Raymarine ST40, you can 3D print a new cover using the file available at www.thingiverse.com/thing:4302817. If you don't have a 3D printer, you can send the file to a 3D printing service. Alternatively, you can create a replacement by applying a couple of layers of clear packing tape over the instrument, followed by two layers of epoxy and fiberglass cloth. For a more advanced finish, use a 50/50 mix of carbon fiber and fiberglass tape, then sand and apply a clear finish.

    Not illustrated Disassembly In order to completely disassemble an ST40 instrument, ensure you have a Back Case Removal Tool, Part No. E25031, available from Raymarine. As it is recommended that new inner and outer seals (9a) and (9b) are fitted each time an ST40 instrument is reassembled, ensure that new seals are available, before commencing disassembly.
