UPDATES
- 26.07.2025: Added a Klipper macro for the nozzle brush and a version for the Neptune 4.
INFO
A nozzle brush holder that mounts to the metal plate under the heated bed. There are three versions:
- One for 10mm plastic spacers (Neptune 3 Pro)
- One for a 10mm spacers and 20mm springs below it (see image)
- One for 20mm springs (Neptune 4)
This has originally been designed to be used with linear rails on Y but also works with the POM wheels. Check here for more info on how to install it in that scenario. Thanks to crshngtardis for designing such a nice diagram showing how to mount it.
There‘s also the option to mount silicone wipers for the A1 mini. Check out the adapter by crshngtardis to mount one to your printer.
This mount won‘t work with the Neptune 4 Pro because it uses different mounting holes on the Y-carriage. I might add a version for the 4 Pro in the future.
MACRO
There's a Klipper macro included with this design. It's designed to be easy to adjust to your exact set up and will also work with other nozzle brushes. Upload the file to your Klipper config and follow the instructions at the top of the file. DON'T USE IT BEFORE HAVING FINISHED THE SET UP OF THE MACRO.
The macro can be found in the zip-file.
