Quick modification of Zack Freedman's Gridfinity container for digital calipers.  The jaws on the General caliper number 147 (6") are so wide that they only fit in a 2x1 Gridfinity box at an angle.

Also included a socket for the caliper screwdriver, which you need to change the battery.  I did not include a socket for replacement batteries, as I found myself spilling them out and losing them on the floor.
