We just developed a really cool new accessory for the Othermill that makes your tools last longer and gives your milled parts a nicer surface finish. It also enables you to to see your workpiece more clearly. Win win! We call our new friend the Bit Fan. And the best part is that you can mill your own Bit Fan in 7 minutes!
Update: based on a suggestion from user Peter Luong, we made an STL version of the Bit Fan. If you don't have HDPE but you do have a 3D printer, you can print the Bit Fan!
