That’s not horrible, no way to move your z axis smooth rods around at all? You wouldn’t need much.
These are things no one ever notices print fun stuff with printers, but once it comes down to dimensions and perpendicularity all hell breaks loose. Instead of company’s who sell fully assembled printers spouting of stupid things like layer resolution, or max print speed (both are BS and material dependent) they should give specs like axis perpendicularity tolerances and parallel. I used a big name printer and the to rails were so out of parallel you could travel the whole volume and it forced parts to slip fit that should slip!
