Bit holder for Milwaukee M4 Screwdriver

This print holds hex bits on your Milwaukee M4 cordless power screwdriver.  Versions holding 6 bits or 12 bits are included.  It is a friction fit over the bit end of the screwdriver.  Bits can be inserted by the end, or snapped in through the gaps.

UPDATE:  I have added a version that mounts at the battery end of the screwdriver. 

I sometimes need to use several hex bits when I am using my Milwaukee M4 power screwdriver.  Unfortunately, it is too easy to set one down and misplace it when changing from one to another, or you didn't bring all the bits you need, etc. 

I looked for existing designs of bit holders that would hold the bits onto the screwdriver, but couldn't find any, even by using the search sites like STLFinder and Thangs.  This was hard to believe, but OK.  So I decided to make one myself.

It was designed using Fusion 360. My first version had 12 bit clips mounted all around the tool.   Worked well, but it was a bit much.  I revised it to include 6 clips spaced through 180 degrees.  I am including STLs for both versions here.  

After using the first version awhile, I found it a bit inconvenient located near the power head. So I reduced the diameter a bit and made it to fit at the battery end.  It is a bit more out of the way there.  It is a tight fit. If you want it to mount further up the handle, use a hacksaw to cut through the ring at the bottom,  It will still hold well, but adapt to the diameter wherever you place it.

  PETG seems to be flexible enough to handle snapping the bits through the gaps...  I'm not sure about PLA.  I used 0.2mm resolution, but 0.1 would probably give a better print.  The walls of the clips are only 2mm, so there aren't very many layers to them.  The one shown was made with different colors by necessity... My roll of filament ran out so I kept feeding random scraps of leftover filament into the direct-drive extruder. 

Let me know how this works for you!
I don't charge for my designs, but if you find this useful, a cup of coffee would be appreciated. My Venmo ID is @Techineer. Thanks!
