Mitsubishi Colt Parcel Shelf Replacement Clips

My friend lost one of the clips that fits on the parcel shelf of his new Mitsubishi Colt car, so I thought I'd treat it as a learning project to draw the item in Cobalt (wonderful software BTW, well done Ashlar) and 3D print it - maybe someone else has lost one too :-)) It should save a pile of money if you have to purchase a completely new shelf.
