well peed about making a 3d star for my daughters birthday,not as easy as i first thought then bingo it came to me how to make it simple(major mind block),anyway a few bits to fill in an finish sanding
You're going to need a damn big Christmas tree to hold that thing up.....
Did you work out the angles yourself or copy an existing one? Cracking job either way.
Cut out 16 triangles same size,welded all into 4 seperate pieces,then welded 2 together,sanded it then measured height from one seam to top seam an marked two cuts on each side of triangle if you know what i mean,sit it on top of two already together an weld on,repeat for other
