I have this long changeable Hex driver tool i use a lot on my Quadcopters.
When disassembling something, i wished to be able to use the the bits from this tool in my little Bosch PSR Select Drill.
They dont fit so i made this adapter.

Print it with the side with the hole down, because the first layer tends to be bigger. By doing so that wount be the side going into the Bit.
