How can you join wooden boards stably but temporarily

[himanka]

I might potentially build interior fittings in my company car. I was thinking of using form boards that I'll put together in some way to follow the shape of the space but only in 90-degree angles. Does anyone know of a good system for this since I would like to be able to disassemble the boards to lift the interior in and out at regular intervals, so it must withstand being disassembled and reassembled multiple times. I have only managed to find systems similar to the one I attached a picture of. Are there better systems that might be even better at being disassembled and reassembled? It shouldn't require assembly from the outside, only on the inside.

Great, the first one should work. The second has the problem that the boards have a limited thickness, so it will be difficult to get durability at the rod's attachment.

But thank you very much for the help.

If you have any problems with your purchase, I am currently in Poland and will be returning to Sweden after the holidays, so I can help.
