If you want to make some rock candy, and having a hard time finding something to keep the stick straight and at the right height, while also providing a dust cover, this lid is perfect for that.
Printed on Creality Ender 3 with .2mm layer height and white PLA with 100% infill (for strength). No supports needed.
Depending on the tolerances of your printer, you may need to sand the cover or make the holes bigger in the top for fit. I personally like using a scribe tool to make the holes bigger, and I did need to do that on my Ender 3.
