You will need 2 outer clamps, 2 inner clamps and 2 aligners for the center.

You may need to drill the holes a little bigger depending on what size zip tie you would want to use to hold them together.

Will need 2/22mm Circumference dowel rods, you will have to cut off some of the end. Home Depot has them at 48 inches long. I believe they need to be 46 but measure first.

I have left the model stack-able because I plan on adjusting the Center dowel Aligners to be taller so I can get a second row of filament above the first. I will update and add files as soon as I can.
