MakerBeam 300x10x10mm Beam Black anodised (Pack of 4)

Good for lightweight projects Dont forget to order correct nuts

Great

I bought these extrusions for a diy project, absolutely love them. But, the finish has been ruined due to aluminum chips and shavings left in the packing, and they bag them up so they rub together as well. I expected more from how expensive these are. Good otherwise, if you dont mind a rough finish.

Pretty good and sturdy. Problem is, it is too expensive and no other sources of accessories other than makerbeam themselves. I guess only the M3 Nut is available elsewhere. So if you run out of screws or of attachments, only makerbeam can help... for a price.
