Spool Shelf using 3/4" EMT & 8x10 Metal Shelf Brackets

**Update to Two Part version 2/6/2017**
I updated the 2 part version so it would not extend past the widest part of the metal bracket.
The 2 part brackets will fit on a 110mm x 110mm print bed or larger. The 1 part will fit on a 180mm x 170mm print bed or larger.

I got tired of just having my spools laying on a shelf. I have a nice 3' space above the door which was not being utilized which seemed like the perfect place to put these rolls.

I looked at several designs & started to remix
