About this 3D model

Clips for a refrigerator shelf restraint. I recently moved into a new apartment with a missing bottom shelf restraint. Thanks to MakerBot and OpenSCAD, I can finally replace it! The hole on the left side is a bit more damaged than the right, so I created 2 different clips. One fun exercise when creating this thing was modeling an M5 nut in order to remove it from the model later. I recommend everyone try it. :)
