This a remix of a model originally created by vehicular on Thingiverse. It fits an EGO 530, 575, 580, or 650 blower which can make it easier to dry off your car than the much longer original EGO nozzle. I shortened it to be able to print on a Prusa MK3S and I also made it thicker for rigidity. It feels about as strong as the original nozzle now.

Tips:
Print in PETG for UV protection and strength
Use a brim so it doesn't fail like mine did twice
Change Vertical Shell Perimeters to 4
100% Infill (It adds minimal time and minimal filament on this model)
I used a .6 Nozzle with in .40mm Draft mode for a 5.5 hour perfect print
Line part of the inside with velcro (across but inline with the twist lock) to have a snug fit
