I created a community material google spreadsheet for the laser cutter group I am a part of and it seemed to be well recieved. I have seen 1 or 2 spreadsheets like this on the forums, but they were for one type of material or never really made publicly accessible and editable by anyone. Mine is different as It is meant to be a living document that anyone can contribute to. I think I have every column we need, but feel free to add more as needed. I hope you all like it and proves to be a great resource for all, veterans and newbies alike.
