This is an extension for the XRP Track System. That way you can even install more sensors and attachments. Be aware of your cable management tho.
I did not use any special settings, but the contact of the print with the bed surface is quite small. So if you should know your printer has bad bed adhesion, you should slow down a bit or use brims. But this comes down to your own experience with your printer, it can be printed without any kind of brim, support or slowing down.
My recommendation is to print the file as provided. This way it doesn't require support.
Use the Drive to XRP Clips to mount the rail to the side plate. The notch is supposed to be on the inside, facing the side plate.
Note: I know it would look cooler on the outside, but the sensor rail actually isn't just a flat surface, so in order to give all sensors a good grip, the shape has to be kept as it is.
The author marked this model as their own original creation.
