Guys, I need to make a corner out of aluminium. Its pretty simple shape, but cannot do it in hands, it would need to be done on mill or CNC. Of course, rounded internal corner is fine. I need two, I will drill holes in them and thread them. I need two of these: I put few in different angles to show the details. It is 4mm thick in all sides, made of 20x20mm cube. I neevr used lathe, but I guess easiest way to make it is to take 20x20mm cube and "scoop out" material from one corner. I hope that makes sense. Is there anyone who could make 2 of these for me? Is it easy to make?
