Wanted an easy way to access the smart air restrictor/plunger tube without prying off and damaging the clamps that held the cap on. This new design allows you to slide and twist on the cap, much like the N-Strike tactical barrel lug attachment point.

I've included two designs, one easier to print/use, the other one more effective. The first design is a single part and doesn't have quite as much of an airtight seal than the original (around a 5 to 10 FPS loss), but can be attached/removed by hand. The second design, which has a gasket printed out of TPU that slides over the separate PLA cap design requires a bit more force to get on and off (I usually use pliers to rotate it), but it seems to have just as good if not a better seal than the stock cap.

I've included the source .scad file if you want to tweak/modify the design. This design will not work on the 2021 Slinger SD-1, as the new blue design removes the clips that allows this to attach (as well as removing all the other nice things about the original design).
