This rail is really well-made. Fit and finish are excellent and it frankly looks awesome. I had a bit of twist in my original X beam so opted for this as the fix. Excessive? Maybe. It was an excuse, I admit. I docked it a star because the Github was pretty hard to find (here it is for any interested parties: https://github.com/ben5459/HybridManufacturingPlatform/tree/main/Lightweight%20XY%20Joints) and even there, the documentation was not what I would call comprehensive. A number of inferences had to be made during the installation on my part .

Beware: The Github documentation referenced a number of things in the BOM that are not listed on the Fabreeko page - BUT - Fabreeko included the M3x4mm SHCS, at least on my order, which was a plus.

Couple things to note: the regular SHCS in the Voron BOM for the MGN12 rail are too long for this rail. You will want M3x6 (I didn't have any on-hand so I had to use M3x5). Also, there are a couple of M3-threaded holes in the XY joints that point towards the tool head. No mention of what they're for anywhere that I've found, but I assume they're meant for some kind of bumper for the toolhead to screw in there.

Nice X rail haven't installed yet
