Doesn't look too impossible. Half inch plywood or MDF with a pattern on it that you want to create. Use this strapping to make the band holders, which you can easily place a few screws into scrap wood to make a bending jig to make them all uniform.

I think the most irritating part would be to cut the slits for each band uniformly. Tbh if I were to do this, I'd draw up my plans in photoshop with the band slits, and send it to a CNC shop in town. Plenty of places will laser cut wood if you send them the file. Then once I had that, make the band holders out of the strapping, put it all together and done.
