MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
Here is what works for me in Blender 3D. Select NEW. Delete the default cube. Go to FILE>IMPORT>stl. Navigate to the stl file and import it. For some reason, I need to click ORIGIN>GEOMETRY TO ORIGIN. You may have to zoom the view. Click tab to go to EDIT mode. Select WIREFRAME for view. Hit C for circle select and select some vertices in the column. Right click to turn off circle select. Now hit CTRL-L to select all linked vertices in the column. Hit C again and select some vertices in the capital. Right click out of circle select. Hit CTRL-L to select all linked vertices in the capital. Hit NUMPAD 7 for top view. Now use the drag arrows or CTRL-G to move the entire column to your preferred position. Hit TAB to go to OBJECT mode. Use view SOLID to check your edt. Use FILE>EXPORT>stl to save your edit as an stl file for Printing. Hope this works for you.
