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

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

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

The width lets me add stability to my vertical test bed, for motherboards.

Its 2020 v-slot aluminum. The nuts I used with it fit fine, I didnt compare pricing with any other sources, but it worked perfectly for my needs.

All of my 3D printers have predominantly use these 20x20x length 6mm V-Slot profile. These can be the fundamental building block for all of you CNC projects. 3D Printers, CNC Routers, Diode Lasers, and any other automation project. These aluminium profiles remind me of the Erector Set components from a 100 years ago. Using these structural elements you can build a mockup and/or functional prototype. These aluminium profiles come in other sizes, lengths, and include many accessories available. The 2020 x 400mm profiles are perfect and include an excellent anodized finish, even on the ends.

These are perfect! They are just what I expected. They came neatly wrapped and have a very clean finish. Even the ends have a matching finish. There are no shiny cut ends.⭐️⭐️⭐️⭐️⭐️

I picked these up so I could add some parts to reinforce my 3d printer, and this is exactly what I needed. The sizes are easy to select, and theyre exactly the same type of extrusions (2020 aluminum) that are used to build the frame of my 3d printer. The edges are chamfered and not sharp, and the channels (v-slots) fit the typical extrusion assembly nuts without any issue. These are a good value for the price, definitely recommend if youre looking for 2020 extrusions

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

They work great, look great and both ends on each piece were either painted to match or anodized. Both pieces were flawless and I will purchase this brand again.

Its difficult to review these - its exactly what I expected and as advertised. Each piece was individually wrapped, theyre straight and true. No damage or defects. Im using these to extend the Z axis on a 3D printer and theyre just what I needed.
