Clamp style X-End with 624 bearings (Q58869)

Wanting to put my bearings from the original Mendel to good use instead of bushings, I modified the original Aleph Objects X-end clamp to hold a similar bearing configuration as the original Mendel. I have removed the motor mount as I still have a vertically mounted x-axis motor and don't wish to change to horizontally mounted motors just yet. I also added a mounting place for end stop flags or opto-end stop sensors. These are not at all close to the original Mendel's positioning, but you should be able to bend your flags into place. Version 1: * Created a reusable "top" file so different motor and rod mounts can be interchanged without copying 80% of the scad code. * Added 624 bearing mount in "x-end-bearings" file. * Added m4x30 flag mount to bottom "x-end-clamp" file. Version 2012-01-15 * Adjusted spacing of holes so there is 40 mm of spacing in between the smooth and threaded rods instead of 36. * Removed one of the straight sideways bearing holes - one is enough * Increased angle of angled bearings so the nuts don't collide (new angle is 135 degrees, I think) * Reduced height above top holes to save plastic. Uploaded SCAD and STL files are always the latest version.
