2 different versions of a doorstop, one with ridges and one without. I recommend printing these using tpu or other flexible filaments so as to not break under the door, I would recommend 60-70% infill with TPU as it is quite soft. they print in place either on the bottom (no adjustment needed in the slicer) or on their side (you may need to rotate them manually, some slicers have an option to place them flush on any surface)

happy printing!
