4pcs 700mm 2020 V Type Aluminum Extrusion Black European Standard Anodized Linear Rail Aluminum Profile Extrusion for DIY 3D Printer and CNC Machine

Good quality very well made.

ok

The brackets are fine and so are the T nuts. But to save you some grief, buy some decent bolts. The ones supplied are made of monkey metal and the socket head rounds just from looking at it too hard. Shame as otherwise good value.

I picked these up as a test for building out a camper and wanted to see if this thinner profile could help with infills and additional tables for a camp kitchen and they are very strong and the anodised coating, although not the most robust i have seen does look very good in black.The profile seems to follow the standard so fixings and angles work as expected and its all square with no distortion which is the main thing. Reasonable value for money

Bought to replace some 400mm 2020 Vs and found that there was a big difference in how the wheels ran in the Vs. I had to re 3D print some parts with the wheel shaft holes 2mm closer together as there was not enough adjustment in the off centre bearings to makeup the difference.

there's not a great deal to say about these extrusions other than they are nice and straight, they are well finished and work perfectly with my third-party 2020 fixtures and fittings.very happy with them.

Items scratched and chipped.
