Case for Arduino


For the case I made for my alarm controller, I want to put an Arduino nano sticker on it. If the Arduino is open source can I use Arduino icons with no copyright problems on a sticker I have made? also, does anybody who has made cases use a fan? here in Tucson, it gets hot a black case in the sun will be warm if not hot. the summertime day temp can be 115 or more. I think I need to have a fan on a case outside.

The code is open source. The Arduino logo is copyright.

Thank you. since I'm not selling the case only showing the solution I used in a blog about making an Arduino-based security system. I have no intention of trying to claim I represent or make Arduino.
