About this 3D model

I made this thing in order to clamp my ShapeOko 1 down to it's support. The piece is slightly smaller than the 80mil height of the ShapeOko front/back plate. It's 78mil height so you can really grip those plates into place. I made those because i cannot access the default feet that are used to hold down the machine. I'm using Outside belt plastic parts (http://www.thingiverse.com/thing:45455) but i cannot access easily my feet clamps. This thing was made with Tinkercad.
