This is a very basic tool for testing hole sizes for various screws.
Every printer is slightly different in its specifications and capabilities. I wanted to make sure that the screws I'm using will work effectively on the various projects I'm developing, so I made this tool to ensure the screws will fit correctly.
This is basically just a set of increasingly larger holes, from 2.0 mm through 6.2 mm, in 0.2 mm increments. I have included a reference image that will enable you to quickly identify the size that fits best.
Many printers have more than one print resolution. I would recommend printing one of these for each resolution you plan to use in your projects.
