                 to a file you can download and cut yourself (either with a laser cutter or to
                 use as a template), as well as a link where you can buy the pieces.
                     • 10 in wide aluminum flashing (usually sold in rolls; you need about 2 ft
                        length for this project)
                     • 5mm bore shaft collar with set screw (McMaster 57485K65)

                     • 18 in length of 1/2 in outer diameter aluminum tube (McMaster 1658T45 is
                        8 ft long but a good value if you have the means to cut it down to 18 in—a
                        hacksaw will work)
