10 Pack ZYLtech Silver 2020 T Slot Aluminum Extrusion for 3D Printer and CNC - 10X 1M

I can't say if these would be good for making a 3d printer or something requiring really high accuracy. They may be that good, I just can't testify to that. But they are great tinker toys for use around the shop. I can't say that I love the connectors that much. The screws are a little weak for industrial purposes. But the price is unbeatable, and they do the jobs I'm asking them to do. So I'm a happy customer. Note that these are probably a little smaller than you might think they are. I ended up buying some 8080 (4 times bigger) for my more industrial requirements.

Good 2020 Extrusion and worked perfectly for my needs. I would definitely buy again if I needed.

I just have one problem. The inner hole is 5.2mm. So it CANNOT be threaded for a 5mm screw. They also sell these end cubes to connect extrusions together, but those end cubes use 5mm screws. So be warned. Other than that, great for projects.

I was a little reserved when buying these but I am very pleased with them. Very well packaged, they are individually wrapped in sticky film, bundled with bubble wrap and plastic film, and double boxed. The anodizing is flawless, surface is smooth, the ends are clean cut, they are really straight, they have no light under them when I lay them on the ways of my lathe! They are more rigid than I expected a 2020 x 1000 extrusion could be, as I have had 600mm extrusions in the past that were wimpy and bent easily. These are not flimsy soft pot-metal!

Priced better than aliexpress and other Amazon sellers. Good luck finding a better deal on aluminum extrusion. Each extrusion in coverer in cling tape to protect them.This is literally 20mm x 20mm. The brand 80/20 sells 1" extrusions. Just know these are slightly different products.I'll elaborate on my review once I get my hands dirty on a project. I'm gonna use this to build a custom car roof rack, a in-vehicle tv mount, and storage cubbies for my SUV. Can also be used to build CNC machines, modular desks, 3d printers. The world is your oyster mate -- build something great!

The 1m long extrusions arrived bundled in a 10pk and each is individually vac-wrapped to prevent scratching. A bit tedious to unpeel and goo-gone the residue but worth it. Rails are straight and flat and the 6mm Euro 2020 fittings from Befenybay, Boeray and Fullerkreg fit nicely. Would order again.

Packaged well, nice 2020 extrusion, but overpriced here.I could have had 10M of 2040 from Zyltech directly for the same price.

I really like the quality of this extrusion material and the price is also very competitive. Perfect for small projects!

Je l'ai utilisé pour monter un simracing seat. C'était parfait!
