Metal Straw Cap

Keep pests out of your drink. Use this Straw cap.  I've included a parametric (customizable) file so you can adjust the length and height of the tether and cup.  It seems to turn the model when you save it. Just make sure that when you import it into your slicer, the cup is pointing upward; this gives it the best strength in printing.
NOTE: Use TPU or a flexible filament.
