We have this bottle of olive oil that always leaks (can't be just us right?) so instead of having kitchenpaper always underneath the bottle, I made this little tray.

Use it for your olive oil bottle, or something else entirely, it's up to you.

I used an infill of 25% to give it some more sturdiness, but you should be fine with 10-15% infill if so desired.
I've also added some supports for the bottom half as i've noticed that without supports the outer walls of the lower side of the roundings may not stay in place.
