Drill Bit Index for 3.17mm shank bits

cults3d

Index for 3.17mm shank bits, it can hold 24 pieces. This is made to fit into the small storage system boxes I uploaded here http://www.thingiverse.com/thing:1493275 but of course it can be used independently. To assemble the index use 1.75mm filament as hinge material, just insert it in the holes. If the fit is too tight use a 3.17mm drill to enlarge the hole.
