Stabilo Woody colored pencils are very soft so they have to be frequently sharpened.
With this adapter, you can spin them with a cordless drill to get the job done fast.
Inner diameter is 16 mm to create a tight fit for stabilo Woodys.
For best results, I printed it with the thin bit down and with supports, so the inside of the adapter stays smooth.
