Shelf Brackets

Summaryhad a glass shelf that i wanted to sit one of my desktop computers to give me a little more desktop space and i didnt trust the shelf on its own to hold the 33lb case so i made a few different braces or brackets whatever u would like to call them. my little shelf is glass so i didnt only need holes to mount it to the wall so i made a few different version some only has 2 holes cause it will have rubber on top since it will be sitting under glass while the others have 4 holes 2 to mount to the wall an 2 to secure it to the shelf. one of the brackets have alittle gap at the back to fit flush against the glass on my shelf but i also added them without the gap. hope someone else finds a good use for these. i also try to make it so it was easier to get to the screws an with a couple extensions for my drill or if u have a long enough driver bit or screw driver it should work better than others ive used in the past.
