6L Ultrasonic Cleaner Magnetic Hold Down Bar

I often use small jars with solvent inside my ultrasonic cleaner with small carburetors. The jars would float and tilt on their side and end up leaking gas or letting water in so I made this bar to fix that problem. I used a $2 magnetic base from aliexpress but you could use old hard drive magnet, round neodymium magnets, magnetic phone mounts etc. For plastic jar lids I just hotglue a steel washer to the lid. I added a skinny one with and without holes as well. You could use 2 or 3 of them to hold down large containers without needing magnets. I also added a wide one with cutouts to reduce the amount of filament. The lip on my 6L tank is about 177mm wide and this locks on perfectly.
