This is a remix of the rugged frog box from thingiverse designer Nibb31 . I designed a TPU insert for the case which holds a Mitutoyo digital micrometer and has a spot for 3 sr44 batteries. You'll need 8-M3x25 screws and 8-M3 nuts. You may need to ream the holes on the latches and hinge components.
