Hey Mark!
Progress finally!
Print from carbon fiber material.
Where did you source the 40-20 from?
That’s it. It’s just standard extruded aluminum. Same material used for 3D printers and CNC.
You will want to cut it on a compound miter saw to get a straight edge. Otherwise you will have some wobble/shaking when spot locked in strong current
Also make sure it’s long enough so that the head of your TM doesn’t hit the shower rod when turning.
