Bao đựng thước thép Mitutoyo 182-207

Sheath for the Mitutoyo 182-207 (150mm/6") steel rule - or similarly dimensioned rules (12.05mm x 152.45mm x .40mm). Non-affiliate Amazon link: https://www.amazon.com/dp/B0002795AM

One model for PLA/PETG/ABS/ASA, this design was intended to be printed in a rigid material. The model includes some cutouts which allow you to slightly bend the end of the ruler bypassing the end stops on either side. This allows for a secure hold of the rule, while also being easy to remove from either end. 

One model for Flex materials, very similar to the original design by @CooterBaldwin. This model has been resized. Beware: it will capture your steel rule if you print it in a non-flex material.

Hope you enjoy, and thanks to @CooterBaldwin for the design and source files!
