Horizontal working surface angled stand

Stand for any horizontal surface to lift it and angle for a better reach. You could glue stand slot to any horizontal surface and then use this stand with it. You can also print N number of slots and use all of glued surfaces with single stand. You can also disassemble stand for more compact storage and its sturdy enough not to use any glue/furniture apart from attaching slot to a surface. Made it for a puzzle table, cause when I was searching for a similar stand there were none. But figured this could be a separate model, cause it is pretty much usable with anything.
