My initial insert inline-clip design got stuck in the barrel of my Flux due to a misaligned o-ring and in the process of trying to remove it I damaged the original barrel beyond repair. I've since altered that design to have better tolerances to make removal in case of misalignment easier, but in the meantime this Flux still needed a new barrel.
So rather than simply model a replacement barrel, I chose to go the extra mile and design an inline-clip that mates with the plunger tube in exactly the same way as the original barrel. This has the same 4x short-dart capacity as my original design, but with the added benefit of having a much shorter barrel extending past the muzzle.
The author marked this model as their own original creation.
