Can you save 1) the STL file 2) the gcode file 3) Then in Cura to File-> and it will save the project file which has all the settings including how you positioned the model on the build plate.
I'd look at these fies. But my guess is this is a data error. The gcode file is gettig corrupted or read wrong by the printer. This is rare if using an SD card but if you are feeding the printer via the USB that it is understandable. It looks like data is being dropped, missing g-codes make a mess of the print. One more thing, It could be that Cura is generating supports inside the screw holes. It might not be infill but rather a support Is the pulley dead-flat? and you are printing it hub extension up. If the model is not in full contact with the plate because perhaps there is a ridge or bump that holds some surface off the plat that this cross hatching is the base of some support materials. Cura uses a cross hatch as the first layer of support material. If is best if the base of everything you print is a flat plane. I can't tell without a look at the files. One more thing, for objects like this try "Gyroid" infill type. It makes a 3D patterns like open-cell foam using intersecting sine waves. About 25% is enough for this part. My guess is "data error" is this is done via USB or if there is a ridge on the pulley it might be suport but suort is printed in X and Y direction not at 45 degrees. But I don't know the camera angle.
