Based on the design of the user "keenox".

I made this part in Freecad from scratch and made every parameter customizable. After opening the file in Freecad, you can tweak every parameter in the Spreadsheet. Then you can export the design to an stl file and 3D print.

Please adjust "'Operator Editable Parameters" according to your needs. Internal (Expert) parameters are also available on the spreadsheet but it is advised not to change them unless you know what you're doing.
