Step 1: The Svg File
The file for the drink coasters was created using Inkscape. The pictures for engraving were found on the internet and converted from a bitmap to a vector format using the Trace Bitmap tool of Inkscape.
Step 2: Laser Cutting and Sanding
Due to the extensive engraving a lot of sooth was deposited on the birch multiplex parts. Therefore all parts were sanded using an electric sander and 240 grit paper. This cleaned up all parts very nicely.
Step 3: Assembly
The parts of the storage box were glued together with slow drying wood glue. Rubber bands were used to hold the box parts together.
Step 4: The Finished Coasters
Two sets of coasters were made waiting for a party.
