These are my personal designs for the mantis tool grid sold by Matco, Cornwell tool dealers. Got tired of waiting for them to be released so I sat down, designed and printed my own. I have one of each of the size ranging from 1/4 inch to 1 inch. Also made shallow mounting for height space limited storage areas (i.e. my roll cart). These need to be printed in the vertical orientation with the socket peg on horizontal plane because the base set pegs will snap off when the slightest pressure is applied. I have got tons of feedback and Ive sold a few hundred to co workers so they have been tried and true on top of myself using them daily.
