I need help with designs for an enlarger table.

I have a single post Beseler 67C, and I can enlarge up to 11x14 on the baseboard. I'd like some sort of stand/table combo where I can move the table down a few inches for 16x20's.

And below all of that I'd like some sort of shelf to keep all of my filters and easels etc.

Have any of you ever built anything like this, and/or have any photos I can draw ideas from? It seems like I've seen plans somewhere but can't remember where, and a search brings up infinite non-related conversations about enlargers,
