For those who have printed this, I'm curious about backlash and it this gearbox would be suitable for driving Z axis leadscrews with 8mm thread-pitch? Thoughts?

What is the actual difference between the Printed and Metal versions? I can see different drive shaft bearings being listed, but the use is rather unclear?
