Igus RJ4JP Prusa i3 Single / Double Holder

I was not satisfied with all IGUS bearing holders, I found those one, but it doesn't fit for original Prusa i3 MK2S y carrige.
At first, I remixed it to fit on Prusa carrige. Then I connect them together to be sure, that both bearings are in line. Also I wanted to have two bearings on both sides.
Y carrige is now much stronger and is moving so smoothly and easy.
