Hole Saw - Hole Enlarger

I got the idea from using a step bit to make a small hole larger. There are six different sizes, ranging from 16 to 68mm, labeled as XS, S, M, L, XL & XXL. I uploaded all files to print all together or each individually. 

I personally printed mine in multiple colors and laser-engraved my sizes on the top. To get the white letters from laser-engraving, I made the first layer black and the second layer white so it would show up when I laser-engraved it. Each step is a difference of 4mm and bronze for aesthetics. The uploaded models don't have the sizes on top, so the model will be blank. If you want to have multi-color print like mine, then see the file I uploaded detailing the layers to change colors. These are based on sizes I use, and I may be missing some sizes or combinations. Please feel free to comment and reach out with any improvements I can make to suit your needs.
