This is a cover for a USBasp AVR programmer http://www.fischl.de/usbasp/ I found a nice, simple case from gggkkk on Thingiverse http://www.thingiverse.com/thing:106253 , but it was too tight of a fit for my programmer. This repable is a rotated, repaired, and scaled version of gggkkk's original design. (scaled up the width by 3%). The photo in yellow plastic is gggkkk's as well. He did the work, I just tweaked it to fit around my device. *edit* my programmer is shorter and has different LED placement. I drew up a V2 stl that fits the newer USBasp programmer. This V2 is the image with the green plastic.

Print, install, and profit.
