Needed a way to clean the bearings for my MPCNC that I'm building. I printed this with Hatchbox PLA. Requires a 1/4x20 3' bolt. Remove dust seals, fill canister ⅓ with citrus cleaner, separate bearings with a spacer, use 2 spacers at top or bottom, put lid on and Shake. Remove bearings rinse all the cleaner off, thoroughly dry the bearings, and put a couple of drops of skateboard lubricant on them, and re-install the dust seals. I wrapped the threads with Teflon tape to prevent leakage. Search YouTube for how to clean bearing, for more detailed instructions.
