Tri-bit holder for DeWalt drill & impaact driver

This bit holder was designed for the DeWalt 20v line of tools.  I have tested it with DCF887, DCD791 & DCD996.  The bits fit in quite snug and are held in with a bump that engages with the locking ring on the bits.  Print as is for the right side (looking from the back of the tool) and simply mirror on Z for the left side.  Attach with a M3 button head
