Hexagon with larger screw holes and drill template

I found the original to have much to small of slots for screws, so I remixed with larger slots. Alignment/drill guide can be used to ensure that alignment to adjacent hexagons is perfect. Screw slot size increased to use 5mm OD screws. Max screw head diameter is 10mm. Should be OK for #6 or #8 pan head screws, I am using #6 screws.
