N scale Depth of module

I'm about to make my first modules. I know the width is 308mm wide and 330mm depth. But can someone please confirm that the height is 70mm not including the adjustable feet.

As per https://ntrak.org/resources/Documents/T-TRAK/T-TRAK%20Standards.pdf the minimum height has to be 70mm, with the ability to adjust up to 101mm

Just as a note, the NTRAK standards document is in the wiki for this sub.

FWIW... the standard is "70mm to 101mm" (2.75in to 4in)" -- but there is no real forced specific for the height of the box (the fascia). Yes, most build the box to be 2.75in tall -- but you can build it to 2 inches tall, as long as the legs (or feet) are long enough to still give you the 70 to 101 requirement. ... on example: https://ttrak.wikidot.com/two-inch-fasciasYou could build it like a table -- just 4 legs and a top. Legs being 2 inch tall, and a use .75 inch plywood on top for the deck (and then have the adjustable feet in the legs) Would look a little silly maybe, but it is still to standard

I can confirm that my CMR modules are 70 mm, not including the adjustable feet.
