OUYZGIA 2040 Aluminum Extrusion 350mm 14 inch V Slot 2040 Extrusion for Building 3D Printers CNC Machine (V Slot 2040, 14 inch, 350mm, 2pcs)

These are exactly as described and well made. This for me is gonna be part of a cnc routers gantry system.

No issues. Good quality and finish. Product arrived extremely well wrapped on time. Five stars from me.

The ends are anodized, seems to be good quality and a good value.

Good quality, decent price, and accurate length. Also, all 6 side are anodized. I would (will?) buy them again.

I grab these extrusions whenever I see a good deal. I use them for projects, repairs, anywhere I need infinite adjustability and versatility. The black anodizing is attractive and tough. Love these.

I needed a few more 2020 300mm v slot extrusions to complete my 3D printer, specifically for the bed mount. This 4 pack was just what I needed, and I chose this set specifically because the ends are also anodized, and not bare aluminum like most other v slots I saw on amazon. They arrived well packaged in bubble wrap and inside a box, all individually wrapped in paper. On inspection, all four are perfectly straight, exactly 300mm with calipers, and all the exact same length. The mounted perfect for my bed, with no warps in them. Overall very pleased with these v slot extrusions on amazon

These aluminum extrusions were what I needed to extend a small laser cutter. Standard tslots fit with them and the black coating has held up well.

These aluminum extrusion pieces are accurately cut and beautifully finished. They work very well for custom 3D printers, CNC machines, laser engravers, etc. I highly recommend them!

For those not on the metric system, these are 23.5 inches long. They measure exactly 20mm in height and width. These have a smooth anodized finish over the entire surface, including the ends. They are straighter than I have the ability to measure. Should work for lot of purposes, including the CNC setup

I have ben getting a lot of these extrusions that come shipped with aluminum bits all over them. These came wrapped well and clean. The finish is excellent and they are straight!
