This is a simple mount for a silicone brush to wipe the K1's nozzle with. It mounts to the rear where the plate is attached. See pictures for details. Reuses the same screws.

For the brush, you have two options:

---
Option 1:

Use a generic high-temp silicone brush (I used this one) and cut it very short. The total length of the mount + brush should be no greater than 5-6mm.

Option 2:

Thanks to Kingkong411 for creating the mold STL, you can use generic red gasket silicone to mold a brush that will fit. This is still being tested and in my tests, may split on you. That being said - I have zero experience with silicone so YMMV.

With either option, I used glue primer and standard super glue to adhere the brush to the mount. 

Once installed, add a macro to clean the nozzle (make sure the nozzle is heated so it cleans thoroughly if you're still using PRTouch). 

1. Add CLEAN_NOZZLE to your start macro before leveling.
2. Add a macro to actually clean the nozzle. The below is my macro I have adapted from others as well. Do not blindly implement this - feel free to use this as a base and test with your setup. My printer has been de-crealitized and I have replaced bed leveling with a Cartographer since.

CLEAN_NOZZLE macro attached as documentation.
