MP Select Mini V2 gantry support remix mashup for block bearing

I wanted to be able to use a single bearing block on the end of my gantry. So I designed the block, then remixed the awesome bracket/side cover done by jprochazka. The holder for the linear rod needed to be moved to accommodate the lack of offset from using this block bearing dead center of the gantry. I also wanted to use an 8mm rod instead of 6mm.

The belt idler must be installed before attaching the bearing to the gantry block. Kind of a pain, but how often do you have to pull the idler
