Cutting square tubing is no harder than cutting molding around a door frame. Use a miter saw. A fine tooth hacksaw blade works well for carbon fiber.
My mitre saw is a 12" Bosch chop saw, the fawncy high $ articulated one. And I've a new carbide blade. New & carbide=dull.
If you don't have a miter saw, print a plastic guide block that holds the tube and has a slot for your hacksaw.
I have considered that too, but in the form of an 18x18mm stuffer that's sacrificial.
Finish with a sanding block to make the edge nice. I've cut a lot of fiber tubes, sharp saws work well. but glass and other fibers dull tools really fast. You can make a really strong part by gluing fiber tube into 3D printed blocks
That is essentially what I have in mind. But moving the tube sideways so one run of the X belt runs inside it. Shorten it maybe 10 mm, and mill a couple slots in the other ends idler so it remains adjustable. Shortening it a few mm will lengthen the belt and narrow the carriage, gaining back some X room lost by the basic design and even more lost by my 4 wheel carriage design.
Somewhere along the line, move the x home sw to the left end where they were too cheap to use 6" more wire to reach it. That will require rebuilding marlin or klipper. Shrug. Turn the whole axis end for end and put it in some cable chain I already have. Neat but flying weight for the Y motor to throw around & its in trouble already on an Ender5plus. It loses Y home, I suspect because the way undersized psu is folding back when using gyroid infill at more than 60 for speed.. Everything else it can run at 200 or more. When I get done playing, the bed heat and motor load will be removed from that supply, bed heat will be 62VAC, and motor power will be a 650 watt 48 volt supply.
Take care & stay well. Cheers, Gene Heskett. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
