Well... I'm not that handy....BUT.... there is a place near my home that sells aluminum and food grade metal. and they do cuts and dril. Problem is that if you look at YouTube video you will see that there is not only a hole but an indentation so the plate would sit on the truffle with max contact. Otherwise i would cut and dril it my self. Monday i will order box of truffles and rake a tray to this place to make sure they cut and drill it correctly
