A doorstop where you don't have to bend down to get it in place or try to position it with your feet. The door glides over it when opening and is released by pressing on the top of the doorstop.

Prints in place as one part using a compliant mechanism for the hinge. The model provided is for a gap of around 8mm, though the model is parametrised so you can customize it to fit your door to floor gap if you wish, I'll post instructions along with a more friendly FreeCAD project when I get time. 

After printing remove the brim and insert a medium size Command strip to stick it to the floor.
