How to build an open storage box, 12" × 8" × 6"

Cut list

Step by step

1. Smooth the panels

   Sand the cut-list panels and dry-fit the box before fastening.

   • Sand the panel faces lightly with a 150-grit random orbital sander.
   • Ease the exposed edges with the same abrasive.
   • Arrange the short ends between the front and back.
   • Check the wall assembly against the bottom panel.

2. Join the four walls

   Clamp the walls square and screw the front and back into both end panels.

   • Clamp the front and back against the short ends on a flat bench.
   • Mark each screw line 3/8" from the front and back panel ends.
   • Mark screws 1 1/2" and 3 3/4" above each panel’s lower edge.
   • Drill 1/8" pilot holes into the end panels with the cordless drill.
   • Enlarge the outer-panel holes to 3/16" with a shallow countersink.
   • Drive the eight 1 1/2" screws until their heads sit flush.

3. Attach the bottom

   Invert the wall assembly and screw the bottom onto all four wall edges.

   • Invert the walls on a flat, padded bench.
   • Clamp the bottom flush with all four outside wall faces.
   • Mark screw lines 3/8" inside all four bottom edges.
   • Mark long-edge screws at 2", 6" and 10" from one end.
   • Mark short-edge screws at 2 1/2" and 5 1/2" from the front.
   • Fasten the bottom with ten 1 1/2" screws through prepared holes.

4. Check the finished box

   Set the box upright and inspect its edges and fasteners before use.

   • Set the box upright on a flat surface.
   • Inspect every joint for gaps or split plywood.
   • Smooth any remaining splinters with the reserved abrasive.
   • Wipe away sanding dust with a dry cloth.
