thingiverse

The Centralizer for Z Rods is a device that fits snugly into the top frame's hole. Its purpose is not to provide a tight seal around the Z rod, but rather to occupy the space between the hole and the rod, thereby eliminating wobble in the Z axis rods. It slides effortlessly into place with minimal effort required, making it easy to use. Additionally, it enhances the overall appearance of your frame.
