ProtoArc XK01-TP keyboard hinge lock

I love my ProtoArc XK01-TP bluetooth foldable, mobile keyboard with track pad. The oly draw back is that you can only use it on a flat surface, any pressure say when using it on your lap causes the sides to fold up, and makes it difficult to type. So, I designed these hinge locks so that you can use it anywhere!Boost MeIf you find this model useful - consider giving me a boost .
