Aluminum pipe was sawed to 3 same parts - 15cm each one.
In a base plate I drilled 3 through holes and then hollows, about 5 mm depth.
On the next step I attached top board to the base in reason to drill 3 holes in exactly places for pipes.
I did one layer coating and after the drying is a last step – an assembly.
I used 3 screw rods and decorative nuts (M6).
So, if your friends invited you to BBQ - this tray can be a good present for them :)
