Simple PCB intended to test PCB fab house capabilities when it comes to using PCBs as front panels for electronic projects.

Testing:

• various colors (silkscreen, soldermask, uncovered copper with finish, bare PCB core)
• using large silkscreen areas as means of coloring
• copper pour hatchings with various settings for different panel surface feel
• inner cutouts and slots and with border radius of 0 and 0.8mm
• outer edge cutouts with right angles, border radius of 0 and 0.8mm
• large hole with diameter above the maximum drill size, which needs to be routed out by the fab house

Here's my blog post about using PCBs to create front panels for your projects.
