I’m working on a set of nozzles (dual) that attaches via the tool mount. Everything except the compressor fittings coming in is 3d printed, including the flexible hose.
Everything is done with standard NPT fittings, so you can replace the 3d printed hose with a premade deal if you want.
Hoping to have this for the dewalt mount as well, I don’t use the 660 anymore but I still have one I can test with. Mounts to the upper mount.
