Mailbox Delivery Flag

thingiverse

This is a mailbox flag that lets you know if the mailman has come or not. It also let you know if some other family member has already taken in the mail. My mailbox is a Gibraltar model ES15. The mailbox flag attaches to the mailbox with friction only, so if you have a different mailbox you may have to adjust the width of the gap to get it to hold to your mailbox. I've included the Fusion 360 file in case you need to modify it for your mailbox. You can also use <a href="http://www.tinkercad.com/">TinkerCad</a> to modify the .stl file. <p> To assemble it I just put a little bit of super glue in the pin hole and attach the flag with the pin. <p> You may not want to use this if you are concerned with people stealing your mail since this will also alert them there is something in your mailbox. <p> <B>UPDATE</B>: I added two more files which implement the pin as a screw. This eliminates the need to super glue the pin in. For this you will need the mailbox_screw.stl and the mailbox_threads.stl files that contain the threaded pieces. The bolt not only secures the flag but it can also help hold the base to the mailbox. You probably do not want to print at a layer height higher than 0.12 due to the fine threads. <p> The original "pin" version of the files are still available for those who would prefer that implementation.
