This is a holder for drill bits in the gridfinity system. The drills from 1-10 are in steps of 0,1mm; from 10-16 in 1mm steps whith the addition of 10.2 and 10.5.  I created them to put them on the honeycomb storage wall while beeing able to remove them from the wall easily which is the reson they have a gridfinity basplate. Whith the additional print of gridfinity base plates for the honeycomb wall you can put it up to the wall like I did.
