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. The Doctor became frustrated when Clara mispronounced its name as "two-dee-iss." (TV: Flatline)
The device later appeared in the Remembered TARDIS. (TV: The Mind Robber [+]Loading...["The Mind Robber (TotT TV story)"])
