I first tried to make a keyring of Lando's beach ball helmet he used in Miami but after a few attempts I wasn't happy with the results so I made some other McLaren themed designs with some nice bright orange acrylic. I was quite happy with the end result and they make great summer keyrings.
I have included the design file so if you want to make the keyrings exactly like mine you can skip this step.
But here is how I made the design incase you want to use different images.
Now its time to cut and engrave your keyrings.
The settings you use will depend on the material and which laser you have.
I used these settings for 3mm orange acrylic on a 5w D1 Pro.
Now all you need to do is add a keyring and your project is complete.
