well .3DS format isn't accepted on its own, it can only be included as an alternative to accompany the .DAEs and/or .SMDs and .OBJs (.DAE/.SMD and .OBJ is the minimum requirement for submissions like this though). if you read our model submission guidelines you'll see that we only accept formats that are more widely supported, and anything other than those 3 main formats (such as .FBX) can only be accepted alongside them as extras.
