Magnetic bit organizer for Countersink Drill Bits

Tolerances should work if printed correctly.  Make sure your printer does not shrink plastic when printing.  I had bad luck with cheap PLA, but very good success with PETG.  This model has two bit holders offset from the rest to accommodate stop bearings which are used on the bits for depth control.  You can use if for any hex bits.  Have included Fusion file, feel free to make changes that suit your needs.  I used 17x3 magnets, doubles (sets of two in each hole).  Very hard to put the magnets in, so maybe try gluing few magnets at a time, because they will fight you every step of the way.
