Keyboard Foot
Saw this, http://www.thingiverse.com/thing:697358, when browsing the Thingiverse site and it reminded me of my keyboards' broken riser/foot.
First attempt looked ok but not quite the same and didn't have the locking feel when folding or unfolding the foot. Modified the model slightly and will re-print.
