This design, as well as previous designs, was done in Autodesk’s free 123D design. This is now an abandoned piece of software, that I am still very proficient in. You can download its last revision for Windows (2.2.14) here, but understand that the online cloud storage option no longer works.
The .123dx file may contain sketches, solids, or both needed to render the final STL. and is included to ease part modification for your purpose.
