The first step is to insert the shapes you need: a triangle, a rounded rectangle, a normal rectangle, and a few circles. Then you will need to use the edit node function to make the rounded rectangle longer.

Now, you will need to create the mail shape. To do this, resize the triangle and the rectangle. Then, subtract any overlap. Finally, resize the circles to create the keychain hole and ensure that the outside larger circle is combined.

For this, I used basswood, but I also think that an acrylic would work well as it is very durable.

Now it's time to ensure that your laser settings are correct for your machine. This is for an S1 40-watt laser, and also, don't forget to wear your laser safety glasses.

Now you're done with your keychain and won't mix them up again.
