I designed this to see if I could increase shooting distance and reduce immediate salt spread.  From my personal experience it does exactly that.

This choke tube seems to help reduce how quickly the salt spreads upon leaving the muzzle of the salt gun.  The result is hopefully slightly better accuracy, more power at longer distances and more concentrated blasts of salt.

It slips over the existing orange muzzle device, no modifications required.

Print vertically in the orientation it loads in.  

Please leave feedback letting me know if you notice any improvements in shot behavior and if changes are needed or ideas to improve the model. 

SETTINGS:

4 walls

25% infill

Everything else can be whatever works best for you and your setup.

3/25/26 UPDATE:  A few users had fitment issues, I've uploaded a version with a slightly smaller ID where it slides over the muzzle.  Use this one if the first one is to loose.  Depending on printer tolerances some slight scaling of the X/Y in the your slicer may be needed.
