Bar Keepers Friend Top & Bottom

thingiverse

IMPORTANT NOTE: I'm only joking about the "fire hazard" thing, but my dad is a fire chief and he'd have my backside if he thought I was being serious about fire. Plus, the product's MSDS clearly states that it's not a fire hazard - just use extinguishing media appropriate for the surrounding fire. So if this product does cause a fire, you're doing something wrong! I'm obsessed with Bar Keepers Friend. Although I know there should be an apostrophe in its name, the product itself is perfect. It's based on oxalic acid, which is acidic and corrosive - you probably don't want to breathe it in or keep it on your skin for too long. But it's great at cleaning up things that need an acid-clean and a scrubby, abrasive clean. I use it all the time in my kitchen, so I buy the larger containers (21 oz) from Sam's Club. The problem with bigger containers is that sometimes you don't use them up quickly enough, especially in a home kitchen. If you only use this container once a week, it might take you a year or more to finish it off. This means two things: 1) If you keep it next to your sink - the perfect place for it - water may drip onto the counter below the container. The container's bottom is made of metal, but it's thin and the rest of it is basically a cardboard tube. If you let this sit on an on-again off-again wet counter for a few months, it'll start to leak a little. And since oxalic acid is corrosive, maybe you don't want it seeping onto your counter. 2) Having it next to the sink means there will probably be water droplets flying everywhere if you're as spastic about cleaning dishes like I am. It's a splash zone - it's a sink in the kitchen! You're going to get wet. Unfortunately, the powdered form of Bar Keepers Friend won't stay powder for long if you keep hitting it with water. Every time I buy one of these, first the top gets crusty (ick), and then the bottom starts to fall out (boo). That's just a fact in the kitchen. What can you do? Well, you've probably guessed what you can do: you can 3D print this awesome top and bottom piece! The bottom Thing fits perfectly around the 73.5mm diameter container, while the top Thing fits loosely around the top, so you can easily remove it. Eventually, I might make a snug-fitting top that presses against the metal top and gives you holes, that way you have a flat surface to wipe away if it starts to get crusty. Now, I know what you're thinking: "But what if oxalic acid interacts badly with PLA?" That's right - I don't know. I honestly have no idea if I just put a fire hazard in my kitchen. If you think that there's a possibility that oxalic acid might interact poorly with PLA (or whatever magic filament you want to print this with), please do some research and make sure it's safe. If not, don't sue me! Live and learn, and post a comment featuring the lesson you learned, along with an I Made One, showing the ruins of your life caused by my Thing. Everyone will be supportive to your face, and they'll wait until later to laugh behind your back. You couldn't have known! But I do know that this idea is fantastic, and you'll probably enjoy it a lot, and it probably won't catch your house on fire.

Round it to the 0.5mm if needed. And then I'll upload a special version with an I.D. that matches (tight for the bottom), and an I.D. that is 1mm larger, for the top. We can iterate until it's perfect, and I can even put your name right in the Summary and/or in the STL files themselves. Please don't forget to do the I Made One if you do - it's cool to see people using the Things here!
