Creality Cr-10s Pro v1 Nozzle Cleaning Brush Mount

Creality Cr-10s Pro v1 nozzle cleaning brush mount.  Used to clean your printer nozzle before every print using a macro in Klipper.   This mounts on the front right bed screw and slides onto the roller carriage. I used the standard brass wire toothbrushes and cut off the handle. It slides and clicks in. It does sit close to the heated bed so it will need a higher temp filament.  I used carbon fiber petg and also tried glass fiber nylon.  Both have worked great.  

Macro made specifically for the CR10s-Pro included below.  I copied the nozzle cleaning macro code from Build It Basement and changed the coordinates for the cr10s pro but once I saw how his moved I ended up changing all of the movement code.

Update: 04/12/2024

Added another version that is 3mm shorter.  My first one was with the Wham bam build plate on top of my original CR-10s Pro with it's existing 3mm thick aluminum build plate still on it.  I have since removed that to reduce the weight of the bed and print at faster speeds and needed a new brush holder that was 3mm shorter.  The new file posted has a couple tiny adjustments to make the fit a little tighter on the carriage.  I have not printed and tested with the tighter tolerance myself.  I think it should be fine but there is a chance that it doesn't fit right.  Also added the step file for modifying.

My Print Settings

• Carbon Fiber PETG
• No supports - Prints with the front on the build plate
