TP Protector Mk5

thingiverse

I've had my cat waste my toilet paper too. So, mine does the same thing as yours. After several revisions, I came up with this design. **Design Goals** This is the Mk5, which offers many improvements over my previous designs. My objectives are straightforward: 1. Prevent cats from picking at toilet paper by blocking their access 2. Allow humans to easily access the roll without being accused of ignoring their cats 3. Print without supports 4. Print standing up so that layer lines are perpendicular to the toilet paper holder 5. Provide a narrower access port compared to previous versions 6. Improve over previous designs: Add a hole throughout the shell for the roll holder, making it easier to change rolls and providing more strength against cats pulling on the part. **Result** This design consists of two pieces to make changing rolls simpler while blocking side access to mischievous bathroom cats. The cap and main body have cutouts that match the window, allowing users to spin the roll if necessary from inside the shell when the loose end of paper is inaccessible. **Printing Instructions** You may need to flip the cap over so the flat part faces down on the print bed, but otherwise it should be easy to figure out how to print. It's small enough to print as two separate jobs on most printers, but with my Prusa i3 MK3S, I was able to rotate the slits to face each other and move the parts around to print both at once. With a .4mm nozzle, I used 2 perimeters, .2mm layer height, and 10% infill. The cap is designed with "lips" that fit over the main body, and the gap is .4mm for some tolerance.
