The top is 3/8" ply with a vinyl sticker like you would do to a dash. Peal and stick on if I recall. The whole think is wood and held in place with four screws. All the electrical and air can be disconnected if I need to remove for some reason.
The front, near the dash is open while the side near my left leg is 1/8" plastic sheet. The off white vinyl material I found at the local fabric shop. Want to match the dash as best I could. The gages and switches are mounted in a 1/4" plastic sheet I can remove if necessary.
Other than the wood, plastic and hardware I pretty much everything I found on Amazon. Here's the film I used for the top.

If you plan to make something a few recommendations.
1. I highly recommend not curving the end closest to the dash as I did. Really complicated everything.
2. Don't install the top until after covering. Tuck the vinyl under the top and screw the top on from underneath.
3. Watch the height. You want to avoid covering the builders stickers on the sidewall.
4. Use high wattage 12VDC to 5VDC power supplies rather than 12VDC outlets and USB adaptors. I'm having problems powering the tablet and a dash camera at the same time. The tablet is OK but I can't get enough watts to the dash cam to keep the batteries peaked and the camera powered up. Something like this with 15 watts per USB plug. If what you use is listed at 15W but has two plugs the power is split or 7.5W per plug.

5. Test fit the location for a cup holder before you cut the hole. Mine is a touch to far behind my elbow but generally OK. Considering I don't play very much with the airbags while going down the road I could have mounted all that stuff a bit further back and move my cup holder up.
6. If you wood working skills are up to it including something like a map book or other type of stuff holder in the bottom half would be useful. Probably be my winter project to remake it and one for the passenger side.
