Functional Cornhole Board

In this project, we built a unique casket-shaped cornhole board. This Instructables will show you how to create your own version using wood, basic tools, and paint.

1. Plywood sheet – 1 piece
2. 21” × 30” (standard cornhole top)
3. 2x6 wood pieces – 6 pieces for the walls (frame)
4. 2 pieces: 20 inches (long sides)
5. 2 pieces: 12 inches (short sides)
6. 1 piece: 7.2 inches (bottom)
7. 1 piece: 9 inches (top)
8. 2x4 wood pieces – 2 pieces for the legs
9. 2 legs: approx. 11–12 inches, cut at an angle so the board stands correctly
10. Wood screws
11. Wood glue
12. Spray paint
13. Clear coat spray (optional)
14. Sandpaper, hand sander, or power sander
15. 3D-printed electrical box
16. Measuring tape
17. Pencil
18. 8-inch hole saw or pre-cut hole

Sizes may vary based on our design, but we used approximately the standard cornhole dimensions.

1. Saw (hand saw or electric saw)
2. Sanding machine or hand sander
3. Measuring tape
4. Pencil
5. Hole saw (if you cut the 6-inch hole yourself)
6. 3D printer (for printing the electrical box)
7. Spray paint cans
8. Safety gear: gloves, goggles, and mask

1. Standard cornhole board size is 21” x 30”
2. Hole size: 8 inches
3. Back height: 12 inches

For the casket shape, sketch out:

1. Narrow top
2. Wide bottom
3. Straight slanted sides

Mark all measurements lightly with a pencil before cutting.

What you do:

1. Decide the size and shape of your cornhole board.
2. Sketch the casket shape outline on paper.
3. Mark where the 8” hole will go (8" from the top, centered).

your CAD program, model the:

1. Top board with casket outline
2. 4 frame walls
3. 2 folding legs
4. Hole placement

Assemble everything digitally to check proportions.

Export a dimensioned blueprint.

1. Trace your CAD shape onto the plywood.
2. Cut the casket shape carefully using a jigsaw.
3. Cut the 2x6 pieces for the frame and legs.
4. Drill/cut the 8" hole.

What you do:

1. Sand all edges smoothly.
2. Make sure the casket angles match up.
3. Test-fit the frame under the board.

What you do:

1. Glue and screw the 2 long sides and 2 short sides.
2. Attach the frame under the casket-top board.
3. Keep everything square and tight.

What you do:

1. Cut two 7–7.5” legs at an angle.
2. Drill holes so they rotate up/down.
3. Install bolts or screws so they fold.

Print the box you designed in CAD.

Make sure it has:

1. A space for the microcontroller
2. Battery compartment
3. LED wire exit hole
4. Removable lid

Test-fit the battery pack and controller.

What you do:

1. Connect LED strip → microcontroller → battery.
2. Write a simple code (blink, fade, color wave, etc.).
3. Test the lights before installing them.

Sand lightly before painting.

Apply base coats first.

Let dry, then clear coat to protect it.

What you do:

1. Tighten legs
2. Fill gaps if needed
3. Add clear coat
4. Make sure the board sits level
