The original Tilta FX6 cage side plate needs to connect both the top plate and the base at the bottom. This is a shortened side plate version that only needs to connect to the top plate. The 3/8 threads are modeled in the file, but it might be hard to print. No supports are needed, as long as you flip it upside down in slicers.
