Karcher wanted silly money for plastic nozzles so I designed my own.

Update: 2 more cone nozzles added (90deg & 45deg(currently untested, let me know if you try them before I do) both have a smaller 1.5mm aperture and stamped with there respective numbers so you can tell them apart. This is an attempt to clean up the spray pattern a bit and give the option of a wide and tight cone.

Produces a full cone spray pattern at optimal flow rate for the OC3. The pressure is similar to the standard nozzle but it's not concentrated into a small area making more comfortable for the washing of people, dogs and other animals. Simple push-twist-lock system just like the OEM part. no other components required, just print and use.

For best results print in ABS and acetone smooth to fully seal the part

I've also produced a single jet version which can be found here: https://www.thingiverse.com/thing:3001378
