Chainsaver Aerosol spray nozzle

thingiverse

This is for a 11oz cans of Dupont Chainsaver aerosol chain lube on a bicycle chain. Its a snug fit on the can but if you need it tight i put a set screw hole in for a 3mm x 30mm screw. Push the set screw in from the left side and it should self thread into the undersized hole on the right side. Chainsaver works well and is cheap but amazon stop selling the 32oz jug and i get the spray can on everything. Hoping this makes it easier to apply. Update 2/10/18 Version 1 worked technically but just made the mess land on the floor and not the bike. Also I could not see if fluid was coming out. I made changed in version 2 that helped a lot and makes it much easier to use. Not recommending printing this in white, makes it too hard to see the fluid. Maybe green or light blue. This version took almost 3x longer to print, 6 hrs to print at 50mms. There are improvement that can be done but I have no plans to implement them, the can angle can be relaxed to 22.5 degrees, a curved backstop for the chain, and slim it down a bit. For this version you need a 3mm x 15mm screw and nut Update 8/11/18 The stock spray nozzle does not hold the straw very well so i took one off an air duster and it holds the straw much better. Currently eyeing a duster with the trigger closer to the can so its less awkward to hold. Also the thing gets so dirty from the chain, being made from white pla not an issue. The background turns to a greasy black. Update 5/12/19 version 3 My old print ended up missing so before printing a new one I did a remix and relaxed the can angle to 22.5 degrees. When using an air duster trigger not sure if this is much of an improvement over version 2 but it does use less filament. Still need a 3mm x 15mm screw and nut
