The dimensions of the Revel 723 pump are 2.0 x 3.6 x 0.8 inches, and I just looked up the T-Slim pump, and it says it is 2.0 x 3.13 x 0.6, so the T-Slim is only a tiny bit smaller and ought to fit. I just made this for my own pump. I haven't done any other pump case designs.
Aztec and Maya are not the same thing. In any case, I don't know why people blew the whole 2012 "prediction" so out of proportion. I'm of Maya ancestry, my family is from Chiapas. Nowhere in our well recorded history it said the sun stone (that is Aztec by the way, NOT Maya) was a prophecy for the end of the world. I don't mean to sound negative...And I know it is not meant to be offensive, but this is my culture and history, so it is all very real to me.
