The author remixed this model.
made the case longrer, wide and shorter in height to fit the Haas Tooling 100mm dial caliper and it's foam, which I trimmed from the original size. Used m3x20 screws for hinge and latch, same as original. Also uses original latches.
Also broken into multiple parts to fit on the prusa mini, and replicate the original case design.
