I'm having some troubles with the scaling. I'm using simplify3d and when I drop the files in it has the base on its side and about 3ftx3ft... my printer cant handle the size. I can scale it down but not to a specific size, and also not able to tip it over so its flat on my bed. I'm hoping there is a way to scale to 28mm easy so I can make sure all the parts fit. any help would be greatly appreciated. I'm shooting for 28mm
