A quick easy print without AMS, this doorstop adds a bit of fun to the bottom of the door.
There are two sizes in the profile depending on the size gap 1cm thick and 2cm thick, just pick the relevant plate. If you need an extra thick 3cm I've added a separate print profile of that.

The eyes and mouth print separately and push in without glue. Note they have wedge shape; a smaller side, which will pop in easily to about half way, then you can push home:

Alternatively you can print with an AMS but this uses more filament and takes longer for little benefit unless you wish to print a few and avoid assembly..
