When I saw the video on the Lulzbot Website for the longboard, I decided to make my own. However, I am in need of a cheap but strong material that I can rely on so the board won’t break. I am currently thinking PET. On a side note, I did some research on PET and PETG but I still can’t figure out which is stronger. My price range is Under 30 USD per 1kg or 0.75kg.
