Folgertech FT-5 (and R2) Y rail stiffeners/braces/T-plate

The Y axis is heavily laden with weight and is most critical to keep stiff.

Without these plates the Linear rails only are supported by the bottom plate and two screws, the Z axis rods are there as well, but transferring stress to these is not ideal for bed wobble.

Regular T-plates do not fit due to the rail and the Y-stop fixture is over the 2020 by a few mm.

Fit these with M5 10mm screws and T-nuts, use stiff plastic and 100% infill (mine look gloopy due to 1.2 nozzle)
