I needed a cup with a threaded cap, but I wanted to be able to adjust the measurements of the cup on the fly, so I parameterized the design in Fusion360.

The cup initially comes with an outer diameter of 120 mm and a height of 100 mm. Feel free to adjust the parameters in Fusion360 (Modify -> Change Parameters) to suit your needs, as I've included the Fusion360 file.

EDIT 03/09/2022: I adjusted the Fusion360 file to also include the air gap on the threads themselves and not just the body of the threaded component. Your threads should now actually work as expected. Major apologies to anybody who has printed this file thus far without making any adjustments!
