--UPDATE 3/25/16:--
A few users were reporting that some micro usb cables had interference with the case while trying to plug in to the arduino, so I made some modifications and uploaded a newer version. This just has a deeper cutout for the micro usb, so all cables should now clear. If anyone finds anymore issues let me know and I will be happy to correct them.

Make sure your Arduino Leonardo is safe and stylish with this slim two piece enclosure. Keeps your micro-controller protected, while still remaining functional, as you develop your next project. Headers can be accessed through slots in the top cover, and status LED's remain visible while enclosed. The reset button can also be pressed through small hole in lid.

We think this enclosure looks great when printed in different colors for the top and bottom, and results in a great surface finish when printing with almost any settings. There is only a minimum amount of support required for the underside of the top cover.

The top cover is attached with 4x - M3x0.5mmx8mm socket cap bolts that thread into M3x0.5mmx3.8mm heat set inserts installed in lower part of enclosure. Part numbers have been included below.
