Drill Bit Organizer ø10-13mm for Machinists

A long time ago…. I needed a Drill Bit Organizer for ø10 mm to ø13 mm drills with 0.1 mm increments. But couldn't find one online, so decided to make one myself.

The holes on this Organizer are designed with the same diameter as the intended drilled hole diameter with an added 0,1 - 0,2mm clearance (i.e. a ø10 drill sits in a ø10,2mm hole, a ø10,1 drill sits in a ø10,3mm hole, and so on…) 

All holes should be 0.1 to 0,2 mm Larger than the shank of the drill bit so preferably start printing the calibration piece (shown below)  first. 

The calibration piece is for a ø10mm drill bit, so if it doesn't fit at all, I suggest you scale it up with about 2% at a time (or increasing the total diameter of the hole with 0,1mm at a time) until you get a clearance between the drill bit shank and the hole you are happy with. And then apply the same scaling factor to the complete model.

A tip is to NOT make the holes too tight as it should be EASY to take the drills in and out (if you are a machinist this is especially important to consider because you might have a tendency to work to, sometimes, unnecessary tight tolerances).  If you succeed in the feat of making the holes too tight - you are in luck! Simply use your drills to enlarge the holes.

Mine was printed on the Prusa printer i3 MK3 With a 0,4mm nozzle. It was sliced in Prusa Slicer with the pre-programmed filament settings for Prusament PLA.
