Drill Driver Bit Attachment

UPDATE: "Download All" button is broken. Use the regular "Download" button next to the individual file(s).

Four position driver bit attachment for Dewalt drill driver. Designed to be snapped onto the rear grills on the back of the Dewalt 20v Max XR drill driver.
I created this after I purchased this drill and found no location to store different driver bits. Wanted something sturdy, yet removable to allow for future design improvements.
This is the first revision, and I plan on making improvements after the attachment gets more real-world exposure.
