IXGNIJ 10pcs 48inch T Slot 2020 Aluminum Extrusion European Standard Anodized Linear Rail for 3D Printer Parts and CNC DIY 1220mm Silver(48inch)

I bought 6 sets of these in different lengths and am highly impressed. Sturdy, precisely formed, cleanly cut, individually wrapped in protective plastic, then boxed. They all arrived in excellent condition, no dings, dents or bends. There were a few minor burrs on the ends from the cutoff saw, but they were so minor 1 or 2 strokes of a fine file removed them. Honestly, if I didn't have a file I could have left them as is--VERY nice!

Worked fine for what I needed it for. A bit pricey though.

I’m building a cart for my dog and these are a great start. Lots of connectors to choose from

The extrusion helps in proof of concept design / builds, is so flexible can be made into anything... multiples of power amplifiers... I would not, cannot imagine approaching my ideas with any other product.

Exactly as described. Packaged great and not a scratch on any of them - most had a protective film on multiple sides and they were all wrapped individually in thin, soft packaging foam. They were able to be cut clean and smooth with my normal medium aluminum miter blade. The silver finish is sharp - unlike the black coated profiles, the scratches from normal cutting and building are practically invisible (they also feel smooth, not like a chalk board like the black coated ones). Probably states this in the description, but will verify in case anyone is curious: - These are T-Slot, not V-Slot - End tap is M6, not M5
