One ring to rule them all?

[Rufe0]

Had another idea and amazingly I found a CAD program I actually like, it's a miracle! It's not for everyone in fact it's probably some people' worst nightmare but it's right up my ally. Instead of using your mouse to click where you want something you type it out in a sort of programming language.

This design is sort of in between a fixed and moving gantry. As a result the bed is lighter than a moving gantry design and the gantry is lighter than a fixed gantry design. What do you think?

If your interested in this cad program you can recreate my drawing with this code

color("Azure") cube([900,1500,100]);//bed
translate([38.5,0,100])color("grey") cube([22,1500,23]);//left bed rail
