The mug press in this 8-in-1 Heat Press can handle a max diameter of 3.25" and features a shorter length. It is not compatible for 40oz tumblers. For these, we would suggest our sublimation oven. The sublimation has a large interior of open space with shelves to allow for large and unusual shaped items. The space is sufficient to support 40oz tumblers. However, how many can fit at one time is subject to the dimensions of the particular style of tumbler.
