Z-Axis End Cap for i3

thingiverse

I recently swapped out my i3's 5mm threaded rod for an 8mm lead screw. Although I could have made do with the original acrylic part, I was missing a vital bearing.\nAfter experimenting with other models that didn't quite fit the bill, I designed these new end-caps to securely hold my F608Z flanged bearings in place. I also decided to integrate a keeper within the print to firmly hold the 8mm smooth rods in position.\nI constructed the model in OpenSCAD based almost entirely on the frame DXF found here: http://www.thingiverse.com/thing:39889\nOne of the screw locations differs from my i3, so that was modified from the DXF, but otherwise it's essentially the same as the original DXF.\nObviously, you'll need two of these end-caps. Due to the integrated keeper, you can't simply print two of them as is. One needs to be mirrored, which I was able to accomplish in Repetier-Host by scaling X by -1.
