About this 3D model

i wanted to use some lm8uu bearings for my y axis but i have not been able to find a bracket that i liked, my idea with this one is that you can mount a board to the side or bottom on it, it is a derivitive of this item http://www.thingiverse.com/thing:7755 but i cannot list it has one for some reason. maybe some one else will find it handy too
