Polysher Precision Nebulizer Tensioning Case

thingiverse

Here is a nebulizer cartridge part that will let you set the tension on the wick as it contacts the output plate. This was made to take some of the headache out of upgrading to a melamine or other wick type. The mist is dependent on the capillary action of the wick, as well as the friction between the wick and the output plate. This allows you to fine tune that friction for optimal mist. Enjoy! ______________________________ UPDATE 7/23/17 "HOW TO" Folks have been asking for a "how to" on this mod, so here goes. BOM: 1.) Magic Eraser Sponge 2.) Toilet connector rod or other 3/8" rigid tubing 3.) Printed Manual cartridge and screw (PLA, ABS, NOT POLYSMOOTH!) Disassembly: Pop the black nebulizer cartridge casing off of it's mount (you can push in the tabs with a screwdriver) and put the cart, cotton sponge, and spring off to the side. Assembly: 1.) Sharpen the tubing on the inner and out surface with a file or sandpaper. It doesn't need to be razor sharp, but it does need to be in the form of a wedge. 2.) Using the tubing, rotate it through the magic eraser 1/8 turn back and forth. The slower you go, the cleaner the cylinder you will make. See pictures. 3.) Cut the sponge to 50mm length using an exacto knife. The "factory" edge will contact the inside of the nebulizer, the cut edge will sit on the screw. 4.) place the sponge into the nebulizer until it seats against the silver disc. Don't apply any pressure, just let it sit. 5.) Place the 3d printed cartridge cover over the sponge and snap it into place. 6.) Insert the manual screw and turn it until it just makes contact with the melamine sponge. 7.) Seat the new nebulizer assembly into the factory housing using the manufacturer's instructions. 7.) Troubleshooting - a.) If the machine instantly alarms, add 1/8" turn of the manual adjustment screw clockwise. b.) If the machine does not produce enough vapor, remove 1/8" turn of the manual adjustment screw counterclockwise. c.) If the machine faults after 1 minute, reset it (push the big button) and try again. Usually restarting it works, and this also happens a lot with the OEM cotton wick and cart.
