Sand paper holder

It's a holder for orbital sanding paper. The STEP model is for you to adjust it to your sander, and the other models are designed for the ryobi cordless and the bosch corded. The thickness of the base is 1/2 in because that's the common thickness for plywood, so if you have a thing which accepts 1/2 in squares, your in luck. And if your thing uses 3/4 in or something like that then edit the STEP file. And if your thing doesn't adapt to the size of it, then edit the STEP file. You put sandpaper in it, and when you need to insert it on your sander, just line up the dust collection ports to the holder notch thingies and then push down. Then, you've got a piece of sandpaper on your orbital sander. Tadaaaaaa.
