This is a portable desk. I wanted the ability to take notes on the go, but to then be able to organize those notes so that I could more easily review them and find what I was looking for. I got tired of carrying around note books, but never going back through them to reference the things I had written because I didn't know where anything was placed.
Now I can write on an individual sheet and later, put that into a 3 ring binder.
There is a base that has holes for M3 heated inserts and 2 versions of the top. 1 with holes for M3 bolts (if you wanted to be able to swap the tops. and one without for a cleaner look that would need to be glued and clamped.
If it's too small, scale it up by a factor of 10 Should fit an 8.5"X5.5" sheet of paper
