Z axis rod and bearing cover Prusa i3 reprap
thingiverse
I noticed that the Z-axis threaded rod bearing kept falling out of its hole in the frame on my RepRap Prusa i3. There was already a small plastic piece covering the Z-axis guide rod in the design, but it didn't prevent the bearing from popping out. I created this part to cover the guide rod while keeping the bearing securely in place. This thing was designed with Tinkercad.

Using my Swiss Army knife's awl to enlarge the hole slightly solved the problem, and now everything works smoothly.
