FTN.5 Suppressor Pack - The latest in 3d printed suppressors. Includes a much quieter 22 can, a flow-through rifle suppressor that is as quiet as baffled counterparts, a complete redesigned inside-out nielsen device for pistol suppressors, and a max turbulence PCC can that is easy and quiet
Maelstrom Suppressor Pack - Flowthrough suppressors for intermediate rifle cartridges and 22. Easy construction, replaceable cores

FTN.4 Carbon Fiber - upright unreinforced PA6CF suppressors (if you dont like the look of the new FTN.5 pistol suppressor)
FTN.4 Pistol and Rifle Suppressor Pack - Legacy pack. Includes pistol cans that have DIY and printable boosters, rimfire cans, rifle rated cans, and PCC cans. While the new FTN.5 is more advanced, the FTN.4 has the high volume of testing behind it, and the FTN.5 does not. If you can only print PLA, then this is a better pack for you than the FTN.5
