It appears to be free. for Linear Motion Products

While they're probably good for making FFF printers, they have too much clearance to be used for making precision laser cutters.

Pros
  • Precise linear motion, great mechanical advantage.
Cons
  • Not bad, but...

Good lead screw suitable for Linear Motion lead screws

The lead screw is straight, correct thread, correct thread pitch and good quality. Without pre-lubrication or cleaning, the nut slides smoothly over the thread. I've used this as the Z axis on the CNC and have had good results. And they fit well at an affordable price. I am very satisfied with the quality and the price.

Pros
  • Widely used in 3D printers, stepper motors, machine tools and other devices.
Cons
  • Expensive

The dimensions are small and the quality assurance is not enough. Do not use them for an accurate 8mm system.

The bearings are small and cannot be used with a true 8mm system. Both bearings had an inner diameter of 7.94–7.96mm, while the true 8mm bearing measures 8.00–8.02mm. One bearing even has manufacturing defects such that the ID at one point is 7.90 making fitting an 8mm rod impossible.

Pros
  • Smooth, quiet, low friction and low maintenance, very suitable for 3D printer Z axis.
Cons
  • Quick Start Guide
