End brackets for a spool holder, used with 5/8" dowels. Edit: I originally had this listed as 3/4" dowels, as that's the bin I was pulling them from at the hardware store. I think their bin is mis-labeled, as I get 5/8" when I measure them.Print out 6 copies of the bracket, you will also need 6 equal lengths of 5/8" dowel, and another 3 equal lengths of 5/8" dowel (they can be the same length as the first 6). The first 6 lenghts form 2 equilateral triangles, and the last 3 lengths go between those.
