The SCAD files are from my measuring and coding the part, then export as STL for use in 3d printer.
Please use OPENSCAD to view and adjust if necessary ( some coding is required - please test using the parameters on the left of screen with the SCAD app - change some values and see how it affects CAD rendition ) , then export as STL for use with 3d.
