Saw Stop Spare Brake Holder

I needed a handy place keep a spare brake for my Saw Stop table saw.  I also needed a place to store my dado brake when not in use.  I designed this holder to fit on the side of my table saw accessory cabinet, which sits under the extension table of my saw.  It includes a wing nut to keep the two units in place so they don't fall off when I open or close the drawers.  The main shaft includes a spacer to keep the connector and small plastic tabs from making contact with the drawer side, protecting them from breakage.  

UPDATE:  The first design was not strong enough and the large shaft broke off.  I've updated the gcode to add additional perimeters and 25% infill to make it stronger.
