I did not print the simple flat rectangles, there would be no issue with those. The others did print, including the axles which were doubtful. However, there are several very small components in the set, the axles are the most notable but the skateboard hubs are another, that are difficult to print in FDM. The axles did print but have no strength at all and will not assemble because any strain will break them. The two halves of the train(?) don't match up exactly and should be looked at. The top of the trash can(?) is asymetrical and doesn't really fit the can well. With a little rework I think this will be very nice.
