i had some drillbit's that i didnt have abox or holder for and it was getting annoying having them laying in the box for my drill. so i designed this box in sketchup and printed it, the holes is made to small in the file, but i used a .5 mm larger drill to make the hole large enouf got it to fit. my printers heating element fail half way thru the top part and it was starting to run out of grey fillement so that is the reason behind the colour change.
