Description
This is the changeable nozzle for the Harbor Freight air texture sprayer 2471, which is probably a decade old. The current model number has changed, but I suspect the nozzle fit is pretty much the same. The file is done in openscad which I had claude.ai create for me, and is easy to modify. I parameterized the spray hole diameter at the beginning of the file so you can change it easily, to replace those nozzles you lost. In my case I printed it at 10 mm for a bit larger spray for knock down. The HF nozzles only go to 8 mm. It worked fine when I was spraying texture. I printed it in PLA with supports under the center since it's hollow at the base under much of the nozzle.
