    V-Slot 20x40 Linear Rail 1500mm long

    Posted by Bruce Levison on Jul 3rd 2018

    Received material in about 1 week time from order. Rail came well packaged; stretch wrapped then bubble wraped in a sturdy carboard 4 x 4 x 60 box. As received the V-slot rail was free of any damage or blemnishes. Excellent price for this piece of straight length aluminum extrusion. I purchased 1.5 meters of both the silver and black anodized rails, both are drop in replacements for the Z-axzis v-rail on my Ender 2 3D printer. I was able to extend the z-Axis on my 3D printer to 500mm then to almost 1 meter length using this rail. Rail ends are nicely square cut and the 2 central holes are perfect size for 5mm thread tap. Easily cut to length with a hacksaw in a miter box. Black anodized rail is very slightly larger dimmensions than silver rail; this was easily accomodated for by adjusting the offset nut on the guide wheel of the 3D printer. Based on my experience with other vendors, I will definitely pruchase more parts like these from OpenBuilds Part Store and highly recommend them.
