SD card extension support & cover

Edit:
added an instructable on how to make the extension here: http://www.instructables.com/id/SD-Card-Extension-Support-Cover/

I made an extension for the SD card, and I needed a support to mount it to the side of a project box, this is what I came up with, the cover is to protect the SD card from dust and liquids.
If you need to make your extension, I added a video below.
Edit:
Added a support with vertical holes.
