Microbit Adapter - 4mm to 6.35mm

Since i've changed from a Wowstick to an electric screwdriver i wasn't happy that i couldn't use my bits anymore because they are microbit. With this adapter you can put your microbits onto your regular bitholder. 

For a good fitment i've remixed this bitholder. The original was a bit too loose for my taste and this one fits a bit better. Tight fitment but almost no play for me. 

Changed the dimensions to get a better fit
