DXF file - File:Stockpivot.dxf
Note: the correct large hole diameter in the above is 4.75", which gives 1/8" room around the DOM for effective welding.
Note: the above is used to generate a CAM file for CNC Torch Table cutting and Laser Cutter modeling - for the pivot plate. In practice, a 4.5" OD DOM with 3" ID is welded inside the 4.75"-4.875" hole (Mickey Mouse hole) to generate a pivot plate for a 3" shaft. To generate a CAM file for 3D printing, one must consider the 3" tubing and print out a 3" hole, not a 4.75"-4.875" hole. 4.75" is recommended as a hole for CNC cutting (leaves exactly 1/8" space around DOM for welding) - and a 4.875" hole is recommended for manual cutting to address inaccuracies.

Note
'Needs the Stock Pivot Plate Sketchup with 3" hole, which is the hole after the precision tubing has been welded in. Further, 6 in 60 Buildout testing has shown that the stock pivot plates need to be 1/4" shorter at the rounded part because of conflicts when 2 of these plates are put together from opposite sides in joints. To address this, please generate a stock plate where the half circle begins 1/4" further away from the rounded edge, so that the overall plate is not 16" long, but 15-3/4" long. Leave the curvature identical, just move it 1/4" inch away from edge.
Full Size Design Files, Sketchup
Realistic Design File: Needs 3" hole for exactly how 3" shaft will fit. Lengh of 15.75" as disussed above. - SKP: File:Pivplate1575-3.skp
Full Size Files for CNC Cutting (Acetylene Torch, Laser, Plasma)
Design File for Generating CNC Torch/Plasma Cutting Files: Same as above except the hole accommodates a piece of precision tubing with 0.5" wall - so it is 4-3/16" diameter to allow 3/32" welding gap. This applies to laser cut metal.
Scale Model 3D Printing Files
Design File For 3D printing at 1/8 scale (plate is 1" wide in this case) - Same as Realistic Design File except at 1/8 scale. - File:Pivplatescaled-3.skp
STL File for 3D printing - same as above, exported to STL - File:Pivplatescaled-3.stl
Cleaned STL File for 3D Printint - see STL Cleaning issues - File:Pivplatescaled-3c.stl
==Laser Cutting
For Laser Cutting out of cardboard at 1/8 scale -
Placeholder for 1/4" shorter pivot plate with 4.875" hole (best for welding) - SKP: File:Pivplate1575-48.skp

Notes
This is an official file release with dimensions. Current as of May 17, 2013. Newer versions will be uploaded here.
We can then print these out according to the Ultimaker Post on Using Sketchup for 3D Printing.
