Lufkin 2in Micrometer Box Insert

This insert, 3D printed from PLA, keeps your micrometer from sliding around in the original wooden box. Also includes a slot for the calibration piece. Measures 7x3in. I only have one of these micrometers so I cannot measure other boxes for variations. This insert may fit other size mics as well, but again I do not have any to test. Feel free to try it out and remix for other models. This one is for a 2in 1912 model.
