Cap to mount carpet in Peugeot Boxer

There is no proper way to fix the carpet in the cabin of my Peugeot Boxer. So I constructed a cap with a hole that substitutes the orginal cap. This cap usually only covers the screws that fixes the floor in the cabin. So you should print 4 of them and move some screws into the holes to fix the carpet. I used some additional washers for the screws. Now the carpet cannot move anymore. This cap cannot be used at all locations as the hole below the cap is different in shape depending on the position. This is a complete creation I did on my own by just copying the measurements of the original cap and adding a cylinder with a hole in the middle to turn a tin screw into it.
