A door wedge for door gaps of varying heights. Multiple heights are provided for your convenience, happy printing. 

If your office door is anything like mine, it never stays where i want it to. I wanted a stop that was accessible for both sides of the door, and more resistant to getting booted into and out of place. Currently it is modeled with a smooth bottom, but it can be changed to a cross hatch or other design if grip becomes an issue. The gap is 1.75" (44mm) wide, which should accommodate almost any interior door. 

Would recommend an infill of around 40%, 0.2mm quality or higher
