This adapter, if used carefully can save you a bit of labour, if you have a good screwdriver. Unfortunately as I printed it in PLA it has a tendency to soften, and I've had to melt it and re-set it over the shaft and bit. But if you run it with pauses it does the job. I suggest strengthening it before you print it.
