Summary Substitute 3d print parts for my open source Infinite Castle Design. These parts offer limited options compared to laser cut foam and wood parts but it is way better than nothing for those who do not have access to a laser cutter. For the tower floor, I think you're better off with cardboard so I will not be designing a printable version of that part.
