Has anyone done HGR15 style linear rail on the 20mm side of 2040 makerslide? Looking at inventables cad drawings, there should be enough room to fit the 15mm rail on without a problem. According to hiwin diagrams I've seen, the carriage block rides some 4.3mm above where the rail meets extrusion, and the makerslide bump thing appears to be about 2.96mm, so there should be room for carriage travel. But before I ordered linear rail, I was hoping to see if anyone's successfully done it already.
