Use this tool to quickly make a slot thickness test for your project—no kerf calculations, or math needed. Once you've found a good size with your [Slot Size Tester](https://cuttle.xyz/@cuttle/Slot-Size-Tester-npTv5htPWyr8) you can cut a set from a small piece of scrap material to make sure you are getting the right fit.

## How to Use

We recommend that you cut the squares out of the material you intend to use with your project. Use [scoring](https://cuttle.xyz/learn/how-to-score-on-a-laser-cutter) to mark the numbers.
