REVISION HISTORY2023-09-13: v1.02 - Added the option to create nozzles with wings2023-09-11: v1.01 - Modified the code to allow customizing the skirt height, adding a needle and/or stem to the nozzle2023-09-10: v1.0 ReleasedINTRODUCTIONA few weeks ago, I lost a nozzle on one of my aerosol cans and printed a replacement. However, I didn't immediately share to the community since the nozzle I printed might not work for everybody so I made it parametric!Presenting the Parametric Aerosol Nozzle Generator created in OpenSCAD! This should allow you to replace your lost nozzles given the dimensions you require. And while you're at it, why not make more spare nozzles with varying orifice holes so you can vary the spray volume depending on your application, add a stem or needle to get into those tight spaces!Replace your broken, lost or clogged aerosol spray nozzles today and use up the remaining can contents!USAGE OPTIONSReplace lost or clogged nozzlesPrint nozzles with stem to fix spray cans with broken tubesPrint nozzles with wings for better ergonomicsPRINTING INSTRUCTIONSTo use, download the Parametric Aerosol Nozzle Generator.scad file.Download OpenSCAD here.Open the .scad programCustomize by entering the parameters in the Customizer panel. See Settings table below.Press F5 to preview the design or go to Design > PreviewOnce satisfied with your nozzle dimensions, render the design for exporting by pressing F6 or going to Design > RenderSelect File > Export > Export to STL/3MF to export the final design to STL or 3MF.Slice and print with no supports. Removable supports are automatically generated together with the model for nozzles with needles.SETTINGSParameterDescriptionSpray Orifice DiameterValues are in mm; use smaller values for finer spray; bigger values for broader spray.WARNING: When printing fine nozzles, 1.5mm or smaller, double check that the printed walls don't close the nozzle pathway.  Can Stem DiameterThis is the size of the hole (in mm values) underneath the nozzle where the can pipe/stem will go into.Skirt HeightDefault is 2mm. This is to limit how low you can press down the nozzle. Smaller values means least amount of pressing allowed while higher values allow the nozzle to be pressed down more.Needle LengthDefault to 0. (Optional) This allows for more focused spray or for maneuvering in tight spaces by adding a thin tube built-in to the nozzle or a short tube for inserting a small straw. Maximum length is 200mm / 20cm.Stem LengthDefault to 0. (Optional) This allows adding a stem at the bottom of the nozzle for fixing broken spray can tubes or use on aerosol cans with no protruding tubes that requires "male nozzles"Add WingsSelect No, for regular nozzles; Yes to produce nozzles with wings.
