Key rings and revolving door plates, should be easy with this project. Even easier if you check the entertaining tutorial on my youtube channel. You don't have to subscribe, but I'll appreciate it! A fresh tutorial every fortnight is what is in for you.
Grab either a sheet of wood, or acrylic. If you choose the 2nd one, make sure you have a good extractor ready. These fumes are nasty!
Protect the laser plate with the laminated shield and hold the material placing on top a small weight.
Using a combination of cut and etching settings, the design shall pop out the sheet without any effort.
Depending on where you plan to use it, add a key ring chain, or a thin nylon string for the doors.
And Bob's your uncle!
