2Dis

From Tardis Wiki, the free Doctor Who reference

The 2Dis was a device created by the Twelfth Doctor to return objects flattened by the Boneless to their original three-dimensional state, and from three-dimensions to two-dimensions again. Its name was pronounced as "two-dis", a play on the word TARDIS and the fact that the Doctor can change the Boneless to and from a two-dimensional state. The Doctor became frustrated when Clara mispronounced its name as "two-dee-iss." (TV: Flatline)
