Designed for school labs where you'd use the same label every year. Put you label stickers on to the collar, then drop the collar on to the dropper bottle. In this way, you can take out the collar and wash the bottle easily, while the label stay dry which can be reused later.
Print instruction: Not picky for material. 0.2mm SPEED profile should do. Print with the collar side on the bed.
