About this 3D model

As my Prusa Air type DIY Reprap has the Z motors mounted on the lower side, I needed to somehow "anchor" the threaded Z-rods with a 608 ball bearing on the upper panel. So this is a simple frame to fixate a ball bearing on a flat surface. The frame is attached with 4 screws (I just used 2) to the panel, whereas the ball bearing itself is simply "snapped" into the frame. The provided files are dimensioned for the standard 608ZZ type ball bearing, but the scad file can easily be configured for other types of ball bearings.
