Enclosure tailored for an official Arduino Leonardo. 1/8" thick walls give it some strength and versatility. The bottom of the case has the words ARDUINO cutout for style. I left some extra space around the micro USB port so the Leonardo can be plugged in while in the enclosure. A lid is....not coming! Volume: 1.17 cubic inches ABS Weight: .04 poundsNotes: Do NOT use a fan to create this enclosure, warping will occur The mounting pegs can shift while printing and may need to be filed for a perfect fit .STL file has already been passed through netfabb
