The Solarbotics Arduino Freeduino Enclosure (SAFE) is a laser-cut acrylic case for your projects - now you can buy a clear lid separately.
The Clear lid is like a blank canvas, modify it to do your bidding! If you have a colored SAFE the clear lid also allows you to see your project a little easier. We've even used these lids for displaying our Lolshields.
Whether it be attaching a Solar panel under it, or drilling some holes to mount potentiometers and buttons, the clear lid is available for your custom modifications.
Please Note: When drilling acrylic remember that it is fragile and may crack when drilled with regular high-speed bits, so try to use plastic-drilling bits at slow speeds (on a wood back-support), or use a diamond-bit with rotary tool.
