As always, I have attached the OpenSCAD source file for you to modify and optimize as needed:

• Fromhttps://www.openscad.orgDownload and install OpenSCAD.
• Launch OpenSCAD and open the attached OpenSCAD source file
• Modify the parameters at the top of the file, or even directly edit the OpenSCAD source code.
• Save the changes
• Render design
• Export the rendered design to formats such as .stl file
• Cut it into slices and print it out.
