This is a remix, However I don't remember where the files came from originally. I made these a while ago, and finally am putting them up.
The drill mount will work for both the drill and impact.
There is a sawzall mount and a Grinder mount.
Also included the source file for the tool mount, and a file I came up with for mounting the batteries.
Can't remember what the exact settings were, but I would say about 50% infill and at 2 perimeters. Printed at .2625 layer height.
Print in the orientation shown for best layer strength. Or print with flat side on bed to save on support material.
Print with support for the pegboard tabs and the underside of the tool mount, and also where the battery contact go.
