4 Wheeled Z Guide with tensioners

thingiverse

Preferably, individuals preferred the three-wheeled RE-D-Bot Z guides over the original four-wheeled guides. However, they still believed that the bed could be held even more securely in place. To achieve this goal, the wheel positions have been adjusted to move outward and reduce leverage. Additionally, tensioner features have been added to both wheels on one side to enhance stability. The M5x20 screws now replace the original M5x10 screws on the 20mm wide sides of the guides.
