Prusa Y rail alignment tool
Source: Thingiverse by Jimbo70
The Prusa Y rail alignment tool is a free printable 3D model from Thingiverse by Jimbo70. Although I designed this tool to align the Y rods on my Prusa MK2 Bear modification, it can work equally as well on the Original Prusa MK2. You can download the STL file from the original listing below and print it at home.
About this model
Although I designed this tool to align the Y rods on my Prusa MK2 Bear modification, it can work equally as well on the Original Prusa MK2. Why do you need this alignment? If the Y rods are not parallel and properly separated, stress will be put on the Y rod bearings which will cause them to loosen and wear prematurely. Also, the stepper motors may lose steps because of the stress.
