A door stop in the shape of a cow's face, for anyone who loves cows. This object is an extrusion from an image created by gayatri for The Noun Project.
Its dimensions are 70 × 70 × 20 mm, or very approximately 2¾ × 2¾ × ¾ inches in ye olde unitſ.
0.2 layer height, 3 top/bottom surfaces and 2 perimeters
I simply wanted a door stop in the shape of a cow's face. Of course it had to hold my door open, so I measured the gap underneath my open door at its largest spot and found that it was about 14 mm, so I rounded up to a final height of 20 mm. So the spec for this project was:
- MUST: Be shaped like a cow's face.
- MUST: Be adorable.
- MUST: Be 20 mm tall.
- MUST: Be strong enough to withstand kicking when setting it under the door.
- SHOULD: Have a lanyard hole.
- This requirement came from my Thingiverse searches. While seeing if anyone had made a cow face door stop before me, I found this Thing by KyleLM, which is a door stop that has a lanyard hole so that the user can tie a string to the door stop, and then secure that string to the door knob. When a person with a sore back needs to unwedge the door, they can pull on the string instead of bending down or kicking at the stop. It also gives you a way to hang the door stop on a hook.
Processing the original image
An artist going by gayatri posted a cow head icon to The Noun Project, which is one of the best websites ever. I downloaded her icon as a PNG because SVGs confuse and scare me.
I removed the orphaned dot in the middle of its forehead, and then converted the edited PNG to a SVG using Online-Convert.com's SVG converter.
You're probably wondering why I converted a PNG to an SVG instead of just downloading the SVG to begin with. Well for some reason, Tinkercad doesn't recognise SVGs from The Noun Project as valid images, so it wouldn't import it as geometry. Doing it this way, however, works fine.
Uploading to Tinkercad and forming the geometry
I imported the converted SVG to Tinkercad. Tinkercad ignores all of the whitespace and turns all of the black into extruded geometry.
I pulled the extrusion up to a total height of 20 mm, and then elongated the face to make it look more adorable (see Spec MUST #2). This elongation made the eyes ellipses instead of circles, and I felt that the eyes were too low on the face anyway, so I filled the original eyes in and cut new ones at a higher position with cylinder Hole objects.
To produce the slanted profile of a door stop, I made a wedge Hole object and sized it to overlap the whole cow face. I flipped it upside down and then lowered it until its apex was 4 mm above the work surface. After subtracting the wedge from the face, I had a door stop that is 4 mm thick at its lowest point; more than enough space for infill.
Finally, I cut the lanyard hole using a cylinder Hole that I stretched into an elliptical cross-section, and then angled upwards about 45°. Ellipses print more cleanly than circles, and the angled hole would not grind so much against the string tied onto it.
