Engineer and Thingiverse user John Lawrence used his 3D printer to create a simple and effective device to save his toilet paper from becoming a feline plaything.
His aptly named “Kitten Proof Toilet Paper Guard” is basically a plastic cover with a sliding door that is installed over a roll of toilet paper. While easily opened by humans, it exploits the cat’s greatest weakness—a lack of opposable thumbs.
The device can be printed in four parts and is easily assembled, as demonstrated in the video after the jump.
