Honeycomb Table for Laser Cutter

This is my Honeycomb bed for my 40W laser cutter, it measures 300x350mm 20mm Thick.

its made from 20x20mm Alu Angle, 20mm thick Honeycomb, and the printed corner pieces.

Hopefully is should be fairly obvious how to make this to what ever size you require..

If not i will try to answer any questions!
