This is my version 1.1 of a small printable vacuum table. Default .stl is 11 x 16 cm , the code is GPLv3 OpenSCAD, and it's parametric, so you can adjust the size and thickness for your requirements.  Alignment peg holes will be printed, BUT THE AIR HOLES must be drilled after printing. this is so that you need only drill as many holes as need, and to the size needed (hard to "print" <1mm holes) just drill your your air holes between peg holes, to get to the inner air chamber. This is now updated to v1.1 changes are to control the warp on such a large flat object
