I took the design idea from Robert and iterated on it. I wanted to have a bit of height adjustment and the original design wouldn't look right if I used the standard M4 socket head screws from the spool holders.
It is only tested with the stock nozzles. If you use the nozzle adapter with a V6 Style nozzle that has other dimensions. You might need to modify the STEP-file in Fusion360 to account for the height difference.
I didn't want to use the supplied spool holder so I used the nut and screw that were left over and used them for my nozzle wiper. I also added a second protrusion in the back so the thing would always be level. Therefore it should only fit the Nuts that are used by Prusa. Other nuts (eg. hammerhead nuts) might work, but might cause other issues though.
I used the same style brush as the design from Surfalex2000 and the one from RobertCowanDIY. The only difference is, that I cut off the bottom with some pliers. To keep the brush from moving I added a drop of superglue. The alignment tool I used is the one from Surfalex2000.
The author remixed this model.
I really liked the approach from Robert, but I wanted to have a little bit of adjustability and a design that fits the supplied M4 socket head screws
