Cut the boards using your saw according to the cut list in the notes.
Shape the handle. Mark the 7 3/4" x 3" piece of wood 1 1/4" from the top and then 2 1/2" from each side. Use the Forstner bit to drill two holes. Connect them with lines at the top and bottom of the circles, then cut those lines with a jigsaw to create a handle.
Cut the angles. On the 9" pieces of wood, mark each side 5 1/2" from the bottom. Mark the middle of each piece at the top and use a 1 1/2" strip to create a point on each side of the middle. Connect those two points with a straight edge and cut the angles with a jigsaw.
Nail pieces together. Use the brad nailer to completely nail the frame together. Attached the angled sides to the base with wood glue and then secure with the nailer.
Align the 7 3/4" piece on top of the handle. Glue together. Attach the handle to the sides with wood glue and nail into place. Apply wood glue to the 8 3/4" sides and nail into the place.
Sand the entire caddy with 80 grit sandpaper to start - then progress to 150 and 220 grit sandpaper to make it very smooth.
Finish by staining or oiling the caddy and then adding your bottle opener with screws. Let dry before using.
