2pcs 400mm V Slot 2040 Aluminum Extrusion European Standard Anodized Linear Rail for 3D Printer Parts and CNC DIY Silver(400mm)

I 3D print my own pedal board supports and use these extrusions. They fit perfect and are very strong. Just add sticky back Hook and Loop.

I took a crack at making a roof rack for my "jeep" used these as cross bars. These will accept being drilled and tapped 1/4-20 and I have made 1/4-20 studs using button head bolts. No real problems with the first order. For some reason my second order never arrived but I was almost instantly refunded. But it worked out as I wasn't home that weekend any how. I'll still buy these again.

Box arrived open but extrusions were fine. Using 4 in place of Molle bars on Billiebar rack huge savings.

Perfect as a straight edge for my circular saw. Good thing is I can attach multiple rails for what even length I need.

Exceeded my expectations would buy again, very good quality!

I purchased 5 of the 48" pieces. I cut one in half and made a support bed for my CNC machine. The other 4 that I didn't cut were all EXACTLY the same length. This was a nice surprise. I didn't have to do any trimming to get a perfect rectangle. I was impressed. The packaging could have been a little more robust. The box was damaged slightly, but my v-slot pieces were all in great shape. I will consider these again if needed.

Good quality.

This is a clean cut and great quality extrusions

As advertised.
