Step 1: Laminating (glueing)

I used 3 pieces of scrap wood I had lying around. I glued and clamped them together so that they would be one piece.

I used way too much glue here. Next time I'll use less glue and it'll require less cleanup.

Step 2: Cutting to Sizes

I cut 4 peaces out of the larger block.
Each one was cut to a 1/2 inch.

Step 3: Slots for the Top and Bottom

I cut 1/4 inch deep slots into the top and bottom. For the plastic top and bottom.

Step 4: Cutting the 45s

The measurements of the sides don't really matter as long as both short sides and both long sides are equal.

Step 5: Cutting for the Panel Mount Connectors

I traced all the connectors.
Then used a combination of the chisel and dremel to make the holes.

Step 6: Glueing the Box Up

Make sure you don't forget to put the top and bottom in like I did.

I used tape to hold all the sides together.

Step 7: Final Box Prep & Clear Coat

I cut the top off the box. I'm not sure if this is the best way to do it, so let me know if there is a better way.

I used hot glue to keep the plastic from sliding around. The plastic was from the bottom of an Aldis bag and was too thin for the 1/4 inch grove.

I put two clear coats of poly, sanding once in between.

Step 8: Finishing Up

I mounted all the connectors and screwed down the electronics.

I added some rgb LEDs and loaded retropi.
