This fits a 40oz Stanley Cup lid. It's blank, but if you open it in Bambu Studio, then near the top right click on the T for text. You can choose your font, font size and text to add to the topper. Choose object on the left, then choose the colour of your topper and writing. If you don't have an AMS, just do a filament change either by watching, Or, once sliced, slide the bar on the right down until you see what layer the text begins. Right click, then add pause. Then re-slice. The machine will pause for you at that layer so you don't have to watch.
