297 = 3 × 99, and 297edo is enfactored in the 7-limit with the same tuning as 99edo. It is only consistent in the 7-odd-limit, unlike 99edo. In the 11-limit, the 297e val is the most reasonable, and it corrects 99edo's harmonic 11 somewhat closer to just, tempering out 4000/3993.

The 297cddee val is a tuning for the musneb temperament.
