Modular vacuum table/clamp for small cnc machines

Vacuum clamp/table for smaller cnc machines/routers. It contains modules 50x50mm which, once printed, you can connect as you wish, glueing it toghether. You can make table big as you want, by printing lot of this modules. It contains side, middle, angle and connector modules which, combined, make one whole table. Modules are 10mm high.
It also contains connector in which you can screw in PTFE tube connector for making vacuum. In future i will make vacuum cleaner adaptor.

Print, glue toghether, you can also apply various chemicals for making it shine and airtight. In grooves you can add rubbers for making better vacuum contact. You will probably need to sand sides for better sealing.

Print flat, without support, but make sure you put 100% infill, so therefore it will not make problems when you make vacuum. You can also use some kind of polisher or glue for plastic, which once it hardened it will make airtight seals.

If you have any idea how to improve this design, feel free to post it, and if you make this, feel free to post pictures.
