UPDATE 16. Feb, 2024.
-I made smaller shelf in case you have very narrow sink, or just need smaller shelf for any reason whatsoever.

Are you sooooo done with your cat casually yeeting all of your cosmetics off your bathroom sink into the void? Is the cat also TOO DANG CUTE and you can't just tell her to get off the sink? 

…..Or maybe you don't have a cat and are just clumsy and yeet your own cosmetics into the void?

Yeah okay, then this is for you. xD This shelf will hold your products while also being pretty and practical. 
I love the fact that I now easily can clean sink, since I don't have to move all xy products one by one, I just lift the shelf and clean! Plus, my cosmetics are not swimming in water anymore.

It's made so it's easily customizable. You can just print the shelf, or you can add little leggies so that the shelf is a bit lifted, for easier water drain if you too splash water a lot while doing morning routine. Leggies are different sizes, you can choose whichever suits you the most. If you are using suction cups, it is advised to measure suction cups height when it's plopped into the suction cup holder and print similar size of leggies to that. The regular small suction cup which is 5mm long should work fine with 5mm leggies. 

For extra security, I added little suction cup holders which you can print. They have holes in different sizes (measure your suction cups top), and you just plop it in and stick it to your sink. 

You can print as much as you'd like, I am happy with 4 leggies and 2 suction cups, my cat cannot yeet it from the sink now.

Print setting recommendations:

Shelf - PLA, 20-30% infill, no supports or brim needed. (around 12h-14h printing with Lightning infill)

Leggies - PLA, 5% infill is enough, no supports or brim needed (around 13min-20min printing with Lightning infill per one leggie)

Suction cup holders - PLA, 5% infill is enough, no supports or brim needed (around 10ish min printing with Lightning infill per one suction cup holder)
