Summary

The original design has quite a lot of flex in the Y-axis due to it being a large lever. I printed two of these stabilizers, inserted a 608ZZ bearing into each, fixed it with a M3 screw and screwed them to the T-Block with two tiny (M2-ish) wood screws directly to the block at the front and back.
