Convincor,
I couldn't tell from your picture what the cupholder looks like exactly. This is a design I came up with while trying to noodle out a cupholder design for someone. Does this resemble what you want to do? It is not terribly complicated and if you have some basic woodworking skills I can give you a rundown on how to make it.
