Mounting bracket for filament holder

This is something that I just quickly whipped up in CAD I wanted to use it for mounting a pole or holding a bar on the wall to hold my filament I printed it standing upright and it broke right away so you have to print it laying down as it is stated in the STL file it was supposed to be 6.5 in but it ended up being 7 in and the STL file and it still works out.
