    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 are sturdy extrusions. I have used them in a few projects. they are strong. the black finish is a nice touch. They are also cut to the right size from the start. 5/5

    I got these to convert one of my older 3D printers into a printer with a larger build area. They are straight, and the measurements are dead on within an acceptable amount. I took my hotend off the cross rail from the printer I am modifying and it slid right onto the rails and back and forth motion was very smooth. All the sides and ends are finished. There are no burrs, scratches, or any imperfections that I could see. Another reviewer thought they were a bit pricey, but 4 packs go for about 30-36 dollars so while on the higher end of the spectrum still within the normal price range.

    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

    I got these as part of the modifications to my tronxy x5sa-400, slowly transitioning toward a VZ-bot 3d printer. The extrusions are cut precisely to 600mm and matched up to the tronxy factory frame exactly. These would be great replacement for damaged rails, or if you are building your own 3d printer frame from scratch.

    Great pacakaging. Nice and clean. No metal shavings.

    I’ve bought a lot of silver anodized 20 x X (40, 60 and C type) and never encountered quality like this before! Exactly (ok I do not have a vernier or micrometer this large but…) the same length, I bought two 500mm pieces and stood them side by side on my surface plate. With 10x magnification I could not discern any difference in length, nor could I see any machining marks where they had been cut! There were between 2 and 4 tiny burrs evident within the profile on one end of each piece, and they were insignificant and did not extend beyond any contact areas that would negatively impact any build or joint. On both pieces the ENDS were also anodized, I have only ever seen raw aluminum on end faces in the past, and I have bought quite a few lengths from other vendors! T nuts, both drop in and sliding, fitted perfectly and were standard 5mm size, plus the pilot holes in the ends were 4.2mm and perfect for 5mm x 0.8mm tapping. Great quality and added to my favorites for minimal cut builds for CNC and 3D printer projects I have in mind.

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

    Got this to make my own rotary blade trimmer. I picked the longest available, 600mm 2040. I am 3D printing the blade holder. This extruded bar came in perfect shape, not a single ding on it. It appears to be true as far as squareness goes. I will update with pictures if my project is successful.

    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.
