this is my model of a build plate cleaner tray that i made for the elegoo plate cleaner. the tray is meant to hold it when you are not using it to keep it clean so you dont accidently get it dirty and to also apply a cleaner to the cloth or pad by pouring a liquid that you will use to clean the plate and pour it in the tray and add enough to cover the whole bottom surface than place the cleaner in and it will be wet and ready to use and you can store it like this. i printed this in petg at 15% infil and enabled ironing with my settings to get the perfect flat layer for ironing so it can hold liquid.
