About this 3D model

This is not simply a gravity mount with oversized holes but rather a press on holder that holds the shafts of these screwdrivers with friction so they won't fall out when it's thrown into a drawer. It's made very specifically for this Craftsman set of jewelers screwdrivers that can be found here: http://www.sears.com/craftsman-6-pc-screwdriver-set-jewelers/p-00941106000P?prdNo=33&blockNo=33&blockType=G33
