Planet Eclipse FL BlunderBuss Tip

First fushion360 project of something i've been wanting to design for a while, still tweaking it a bit to use less filament. The ID is a pretty exact fit for the tip of the FL back, all my FL backs ranged from 20.02 to 20.08 at the tip so i split the difference at 20.05mm. I would recommend printing a portion of the back to verify thread and ID tolerance before printing the whole thing.
