The Wooden Case
For the wooden case, you will need to cut it from a sheet of 3mm thick wood.
The design files include two sets of all the buttons so if you lose, break, or ruin them, you get a second chance.
You will also get a bunch of scrap pieces, hold onto them, they're good for testing wood stains and varnishes.
Make sure you have received all of the parts and contact the laser cutters if any are missing or broken.
The pieces are made from thin wood so they will be fragile until they are glued together.
Use your wood glue of choice and follow the directions it gives.
