It uses a self-made backplate, of which I also provide a mod in my profile.

 This back-plate is the weak spot of the printhead, as over time - at least using PETG - it starts to bend forward towards the hotend. The impact of this is that if you are not using linear rails, the distance between the upper and lower POM wheels is increasing up to the point were you can't compensate with the adjustment screws. 

To work around the issue, I designed another backplate meant as adapter to the original one. This way, the original one provides the required stiffness, while the adapter has the necessary holes to mount the printhead.

 

Sidenote: the adapter will result in the nozzle to be slightly higher than using Raidys backplate. The metal z-bar using the original x-axis motor cover was hitting the bottom in my case, which is why I also designed an update to the x-axis motor that you will find in my profile.
