ATERET 5 Gallon Black Metal Bucket with Lever Lock Lid - Heavy Duty 3 Pack for Outdoor, Household & Commercial Use - Perfect for Gardening, Construction, Cleaning & Storage

I only use two of them, but have a spare in case the other ever gets damaged.As for the lids, they're okay, but I highly recommend the one that has the latch that secures it firmly to the bucket.As for how I use it in my setup, I have one dedicated for the washing process, in which, I place either a 2-3 gallon bucket inside w/ its own lid. After that, I place one of those bucket strainers on the 5 gallon and let it loose into the smaller bucket inside. Place my pieces inside, and then pour the cleaner into it.After closing it up with the smaller lid, I can then place a brushless hand massager or other type of vibration device on top, then set a timer for a few minutes. Close the bigger lid and wait a while.Honestly, the double bucket is more to reduce the chance of splashing and messes.Once done, I can remove the pieces by just pulling up on the strainer picking the pieces out with tongs or gloved hands for more fragile pieces.Then give it an hour or two for pieces to dry and ensure no liquid on it.Finally, the second one is used for curing due to how reflective it is inside the bucket.I did have to modify the lid of the one with the latch, by cutting a rectangular hole in the center of the lid, then place a stronger UV LED lamp that is then clamped down by a 3D printed mount, to ensure that it does not slide out of place, and ensure no light leakage. Ensure the hole is centered to the lid, and if you want to increase the evenness of the curing, you could mount a frosted acrylic to the bottom of the lid, and a white acrylic or other UV resistant material at the bottom.I ensure the piece on the center of the turntable with either zipties, or clear fishing line, if it's a piece that doesn't center or lay proper on the turntable.After securing the piece, I then close it up, firmly secure the lid and flip the switch to turn on the lamp.Depending on how big the piece is and depending on opacity of object, it could take some time between 30 seconds to about a few minutes.Once that is done, I turn off the lamp, give it a few seconds to ensure light is off, I even unplug the lamp in case.Remove lid, take out piece, and overlook it to ensure no uncured resin is left on piece, if any is left over, I will try another wash, wait for piece to dry and cure for an additional 15-30 seconds.After all that, I can put the liquids back into the respective container, by placing the original container in the washing bucket, pouring it back in with a strainer or filter medium to ensure cleanliness of it, and store it away.Finally, I can take the buckets outside, and leave them open facing the sun, ensure that any residue gets cured and any solvent to evaporate, and air out the containers so they don't have lingering odors or smells.
