Expanding Foam Nozzle

thingiverse

A simple nozzle to push into the tube of a disposable expanding foam can. It reduces the the flow to make it a bit more controllable. The resulting foam can be used as an adhesive for sheet materials as well as gap filling. I also used a zip tie on both ends of the tube to ensure the pressure didn't push the nozzle out of the tube, but the barbs on the nozzle should be sufficient. You need to release the trigger before you get to the end of a run as the pressure in the tube will keep the foam coming out for a bit. Cheaper than a gun if you only need to do a small amount of work and way better than the wide bore tube that comes with the can of foam.
