I just finished 3d printing a small boardgame table from the StageTop Kickstarter. I wanted to have a portable surface I could use for playing boardgames on a couch, and can then move to a table, and so far it's working pretty well. It has a little bit of flex, but not enough to move any of the pieces.

Here's the link in case anyone is interested (I'm not affiliated with them, besides backing the Kickstarter):
