Today I visited a customer of the CNC machines I sell, besides this machine he has a medium size router he uses to cut airplane models.
He uses 2mm boards, and his main problem when he started was keeping the board flat, so he came with a solution, take a look:
This is the view from the top, the hole in the middle is where the spindle passes thru this gizmo, the side tube its for the vacuum attachment, and the holes on the sides are guiding holes, thru them ride two guides that are attached to the spindle. You can leave this head floating, meaning that it touches the material to be cut, or it can be fixed at some height.

this is the view from the bottom, the radial holes are there to prevent the vacuum lifting the board and to catch the produced debris, the delrin center is raised a little so only the plastic touches the wooden board to be cut

and a straight view from the top.

He also designed a version 2 of this gizmo, inspired mostly by how the sewing machines hold the clothes where they need to be, he does not built it because version one works dandy, here are the drawings:
