Arrma Granite unbreakable roof

This is a strong roof protection for the Arrma Granite that I designed for my car. I think that it is compatible with all versions of the Granite, at least before the V3 (please someone try on V3 and report in comments, it would be great).

You will need:

• 4 x M3 screws
• 4 x M3 nuts

EDIT: I no longer have a 3D printer, so I can't respond to requests for modifications. I don't have any other files than the ones uploaded here. You are of course free to use my work and adapt it to your needs.
