I found the original cambam forum post with the files
And confirmed they used an 1/8" endmill and 3/4" MDF
They included the original file in *.cb format. (a cambam file)
DWP611-Diverter.cb (19.4 KB)
I used a trial copy of cambam to export this to a *.DXF format
DWP611-Diverter.dxf (5.9 KB)
And a online converter to convert that into a *.svg format, which seems to have lost its size info and has some alignment issues But may be a good start point for a Easel version.
EDIT: actualy looking at the original cambam file the conversion is perfect. Which is weird because the files does not match the carve geometry. There is a little "lip" around the outer edge, etc. I am guessing that the rest is part of the cambam cut settings?
I will see if I can come up with a better SVG conversion.
