Most modules are designed with four legs, one in each corner. A few designs use two legs on one end and rely on the legs on the next module to support the other end. These modules, without the addition of optional legs, do not stand on their own. There is even an innovative design with one leg per module that relies on the entire assembly of modules to provide stability. Obviously, these modules do not stand on their own.
So how many legs should a module have?
Why three of course. Oh, and they should not be at the ends either.
Why three legs? For the same reason a tripod uses three legs. Three legs always touch the ground. How many times have you gone to eat and ended up at a table that wobbled? Tripods never wobble they merely tilt. Put a module on an uneven floor; on a module with a very sturdy frame, it will wobble just like a table; on a flexible frame, which is the vast majority of modules, the frame will flex to compensate for small variances and only wobble for large variances. Avoiding flex is the first step in maintaining solid and reliable modules.
