I made this wrench to make it easier to remove the nozzles from our Neptune whirlpool tub ("Turbo" nozzles). If you want to clean the nozzles thoroughly, you have to take them out.
Note that you need to remove the cover ring around the outlet before you can remove the nozzle.
Pictures show the Turbo nozzle when installed, the nozzle after removal and the wrench sitting on top of the nozzle to show how it nests against the nozzle.
I printed this on an MK3.5 using the "0.20mm SPEED" settings and with 3 perimeters and 20% grid infill using Polymaker PLA PRO. Printing with the closed end of the wrench on the print bed - no supports were required.
